[Archers] Fwd: [SCA-Archery] Grand Archery Tourney

Tue May 14 06:33:06 PDT 2013

Words from Sir Jon, the original creator of the IKAC, who is attempting to
energize and organize the archery community society wide.

I too would love to see Atlantia participate in this new avenue of
inter-kingdom competition but this time on a personal level rather then a
group level.  Plus it is based on shoots held at events rather then an
unchanging standardized shoot (read boring).  If you host an archery event
(listed in the Acorn) where more then 20 handbows or 10 crossbows turn in
scores, please consider submitting the scores to the Grand Archery
Tournament (GAT).  If anyone has questions on how to submit scores please
email me either on or off list.

I have noticed both here and on some the kingdom archery sites, that there
are several major archery events either coming up or that have just
happened. If you have more than twenty handbow archers or six crossbow or
both archers you should send the scores from the competitions to the SCA
Scores site for inclusion in the GAT (Grand Archery Tourney) scores base.

There are no requirements for the type of shoots included in your
competition nor a minimum number of shoots.  You can have either a single
shoot in the competition or several.  The GAT scores are based upon the
standings of the archers compared to the other archers shooting the
competition. Figuring out these standings is a bit complicated, however the
SCA scores site does all the work and you only have to submit the scores to
the site.

Over the years I have heard archers complain that they do not like shooting
the Royal Round or the IKAC and that is why they do not have scores to
compare to other archers.  Well ... the GAT allows archers that shoot
non-standard competitions to compare how well they do relative to other
members of the SCA archery  community shooting unique non-standard
competitions, as well as some standard competitions (SSAC and IKAC). You
can compare your ability with other archers in your kingdom and with all
the other kingdoms as well.

All that is needed to do this, is for the those running the competitions to
send in a copy of the scores with the required information from the events
to the SCA scores site. For further information on the rules go to:
www.scores-sca.org/gat  .  Or if you have questions, contact Gladius at:
gat at scores-sca.org

General information on the GAT is included below.

How many of you will be sending in the results of your competitions to the
GAT?

Please crosspost this information to your local archery groups.

Gladius:  Would you like to expand upon any of this?

Grand Archery Tournament BACKGROUND

The Grand Archery Tournament, GAT for short, is a system that allows all
the archers in the Knowne World to compete in local tournaments and compare
their performance to archers elsewhere in the SCA. Many archers shoot Royal
Rounds, IKACs, and similar standardized competitions where the target type,
ranges, and number of ends are the same whenever shot. A means needed to be
devised to record scores and compare archer’s resulting standings in
non-standardized tournaments as shot at most large events where archery is
included. The GAT is an attempt to address this need.

*INTENT:*
The intent of the GAT is therefore to allow scores obtained during
non-standardized shoots to be recorded, and competitor’s final standings to
be calculated based on their performance relative to the other shooters,
and displayed for comparison. The hope is that the vast majority of GAT
scores will come from unique event based shoots, however so that everyone
in the SCA may participate, even if there are no shoots close to them, the
four yearly SSAC shoots and the IKAC will be always be included such that
no matter where an archer is they have five shoots available to them to
build their yearly GAT ranking.

*ORGANIZATION:*
For the sake of simplicity and fairness, at this time the GAT is divided
into only two divisions, one for hand bows, and one for crossbows. A Grand
Archery Tournament consists of one or many shoots, each with a numeric
score. The GAT is meant to be an advanced tournament, but, all archers are
welcome to compete regardless of age and ability.

*SUBMISSIONS:*
Once the shoots have been completed, all of the participant’s scores and
other necessary information may be submitted by the responsible marshal to
the Keeper Of The GAT who will calculate the resulting standing of each
shooter relative to the other competitors. The winner of the tournament
will be assigned a standing of 100, while the others will have standings
calculated as a percentage of the winner’s score.

*RESULTS:*
The participant’s “name”, “kingdom”, “division” (bow type), “total GATs
entered”, “tournament place and date, and standing” are then recorded. A
record is posted to the GAT standings web page. You may contact the Keeper
Of The GAT and request that your standings not be displayed. As scores
accumulate, various other statistics may be added to the standings page.

*QUESTIONS:*
If you have any questions, comments, or criticisms, do not hesitate to
write to the Keeper of the GAT at
gat at scores-sca.org<gat at scores-sca.org?Subject=GAT%20Question>

*MARSHAL ACCOUNTS:*
If you are a marshal, have not already gotten an account, and would be
willing to submit your scores via the site, please send me an email with
“Account Request” as the subject. The email must include your Mundane name,
Scadian Name, Home Kingdom/Group, and Email address. Scores which are
submitted via the site will be given priority for getting approved and
included in the official standings.

*START UP:*
The GAT was initially announced on the community email list in mid-April
2013 with the initial standings populated solely with the data from the
SSAC and the IKAC. To further jump start the initial standings all events
which meet the GAT requirements and where shot between June 1, 2012 and May
1, 2013 are invited to submit their scores should the MIC still have them
available. These back loading event submissions must be entered before June
30, 2013. As the Event Shoots input form will not allow for the entry of
dates older the 30 days, please enter a weekday date (to help separate them
from current valid events) as well as emailing the GAT
Scorekeeper<gat at scores-sca.org?Subject=GAT%20Back%20Load>to let him
know when all of the scores are entered for the event and the
true date of the event.

The GAT Standings during this initial start-up year, May 2012 - May 2014,
will remain a bit wonky as many kingdoms will not be fully represented
prior to the original announcement and events will be entered out of
sequence. However the more events and data that can be added to the
start-up year will help to make the standings after May 2014 even more
stable as the data from back years offers a broader base to build on.
 FORMAT AND REQUIREMENTS

Any archery competition can be designated a GAT. However, if the resulting
standings are to be calculated and posted to the official GAT scores page,
the following criteria must be met.

   1. In order for the keeper of the scores to be able to calculate valid
   standings, a minimum of 20 hand bow or 6 crossbow competitors must enter
   the tournament.
      - JUSTIFICATION - If too few competitors enter either division, the
      scores for that division will not be statistically valid and will not be
      calculated and posted to the official GAT scores page.
      - CONSIDERATIONS - What if you don’t have enough people to hold a GAT
      in your area? 1) Train more archers. 2) Invite skilled competitors from
      surrounding kingdoms. 3) Design a competition made up of shoots
that can be
      reproduced and shot at several events in several locations. So
long as the
      locations provide similar conditions, the standings can be accurately
      calculated. As an example, if there are only 6 crossbow shooters in your
      entire kingdom, devise a tournament that can be set up at two or three
      events that all six crossbow shooters can attend. Announce on
your kingdom
      calendar that a GAT will be shot at the X, Y, and Z events. Once
the shoots
      are complete, submit the accumulated information to the Keeper
Of The GAT.
    2. To be official, the GAT must be shot at an event listed on the
   Calendar of the kingdom in which it will be held. Unlike Royal Round and
   IKAC shoots, GATs may not be shot at unofficial gatherings even if enough
   participants are present.
      - JUSTIFICATION - This rule has been added to assure the maximum
      number of participants the opportunity to compete.
      - CONSIDERATIONS - A kingdom can host many GATs per year. Ideally a
      large kingdom ought to host multiple GATs far enough apart to allow
      everyone a chance to submit a score. If your local weekly
practice attracts
      the required number of participants to qualify as a GAT, simply
announce it
      as such on your kingdom’s calendar.
    3. Equipment that is allowed in your kingdom according to your archery
   rules may be used to shoot a GAT. Equipment that is not allowed in your
   kingdom according to your archery rules may not be used to shoot a GAT.
   4. Certain basic information must be recorded and provided to the Keeper
   Of The GAT by the responsible marshal. This is to include The date or dates
   of the shoot, the place or places where the shoot was held, consisting of
   kingdom and group, the names of the participants, their home groups, their
   home kingdoms, their division (bow type), and their numeric score.
      - CONSIDERATIONS - Ties do not present a problem. If a participant
      was unable to complete the shoot for some reason, the partial
score will be
      provided. If no partial score is provided, a score of zero will be
      assigned. As each year’s scores are based on a sum of standings shot, and
      not an average. So non-completion of a GAT due to illness or an equipment
      failure will not increase an individual’s score, but it also will not
      adversely affect an individuals posted standing.

 CALCULATIONS

The formula the Keeper Of The GAT uses for calculating standings is as
follows.
Each event will be given a Difficulty rating calculated from the full list
of archers attending. This will result in a Difficuly between 50 down to 1.

Based on each archer’s actual score, a GAT Score will be calculated to
normalize out the target point values.
GAT Score = (((Score – Lowest-score) / (Highest-score – Lowest-score)) *
99) + 1
This will give a GAT Score range of 100 down to 1 for each Event attended.
In a GAT where eight crossbow shooters turned in numeric scores of 33, 29,
20, 20, 19, 13, 12, and 8, the resulting GAT Scores would be 100, 84.1,
48.5, 48.5, 44.5, 20.8, 16.8, and 1

The GAT Standing, or each archer’s Rank within the overall community, is
based on multiple scores over multiple years. One great year can bring an
archer well up the ranks, but to reach the very top they must be a
consistent performer. For each of the most recent 4 years the archer’s top
five Event Scores (GAT Score * Difficulty) will be added together. Each
year’s worth of scores will be valued at double the previous year (current
year=10, previous year=5, third=2.5, fourth=1.25 ).
Standing = (Year Value * (Sum of best 5 Event Scores from current year) ) +
(Year Value * (Sum of best 5 Event Scores from last year) ) + ...

KEEPER of the GAT The Keeper of the Grand Archery Tournament is Gladius,
mka Jim Koch, hailing from the Kingdom of the Middle. He may be reached via
email at: gat at scores-sca.org
