Hm. 8 hours?
Anyway. Assuming 2 details. At FITA timings of 4 minutes per six arrows (or 2 per 3) that comes to 3hrs 12 minutes to be allowed for shooting. Then we come to scoring. If we allow 5 minutes walking and scoring for each end at the longer distances, and 3 minutes for the same at shorter distances (and this feels like rushing things), then we add in another 2 hrs 12 minutes. Then we can add in two periods for moving targets forward - depending on the size of the field, lets add another 30 minutes for this. So now we are up to six hours. Add in an hour for lunch (during which the faces also have to be changed, as well as targets moved). So we are now at 7 hours. And, in my experience, a 9:30 start usually gets finished around 5. Not much extra time for sighters. And
GNAS does not give anyone a "bum deal" in this respect. Again, in my experience, because there are no traffic lights involved, we get less of the "look at me" brigade playing chicken on the amber.
As for FITA rules. Again Hm! FITA allows for "practice" on the tournament field, but 3.19.1 states "practice targets will be set up at the first distance" and "Practice will be for a maximum of 45 minutes, but may be less, and the competition will start as soon as possible". Now I read this as stating that practice will only be before the round, not between distances. Sure, there may be a practice field, where archers can practice at all distances, but this is a facility only laid down for specific events. And its use must be within the time constraints of the overall event. Again, the main difference from
GNAS is that there is only one end of sighters. As the purpose of sighters is surely mainly to assess windage, there is no great loss.
Returning to timings, it is not generally realised that, in many countries, a FITA round is generally split over TWO days, with a double over 4!
Sorry to rabbit on at great length, but I do believe that
GNAS gets it in the neck rather too often.
