On a strong day the pre-start gaggles may be much higher than the
maximum start height. It would in theory be possible to exit the
rear, perhaps by climbing through the top adjacent to the rear of the
cylinder then bump pre-start gaggles for approx 10 miles without
descending into the top of the cylinder.

If this is viewed as a problem, we simply limit the option for last-
exit start to disallow flying over the top of the cylinder. (If you do
it, you still get a start, but scored under the old formula. You still
get a score for the day, and you still can start out the top as now,
but there is no advantage to doing it.)

Again, these traffic problems are easy to solve. The big question is,
do pilots want to do it this way? Or do the potential disadvantages in
strong winds, or the "big gaggle" just moving upwind a bit, make it
better to stay with things as they are?
