Bank numbers have not been changed. The layout map of banks is still the same. The difference is that they will shooting 50 per trap.
Banks will be listed on PreSquad.com as: 4a, 4c, 5a, 5c, 6a, 6c,...
You are correct about banks 4-14 being for singles/handicap, and banks 15-27 for doubles.
Also, please make an extra effort to pay the presquadding fees by credit card (or Paypal). The IDNR will pay any handling charges for this shoot. They are doing this because they are really not staffed to open tons of envelopes and process checks. They will appreciate the reduced workload of electronic payments.
I presquaded yesterday and could not figure out how the squads jumped around so much. An event will start out with banks one through twenty-two and skip to forty-seven. Why the holes? Then it will force you to squad on the first go around saying that the next group of banks is too close to the next event. What's up?
The squad numbers are based on a 27 bank system. Not all banks are being used on all events. That explains the "holes".
Also, PreSquad.com will prevent you from squadding late on one event and then too early on the next event. If you think in terms of "flights", this allows the club to begin the next event even before the previous event has finished.
I did not attend the Grand last year and was not aware of how the ATA did the squadding. I want to say that this is the most ambiguous method of squadding I have ever seen at any shoot! This is one gigantic big heap! This detracts from the shoot being well run. Thanks for your clarification. Gary
