Here's the solution to the problem that someone might

at 300' to get up
to 500' and save himself the rolling-finish penalty:

There is a donut of airspace, from 1 mile radius to
(say) 4 miles
radius, with top at 500 feet

It's the Krispy Kreme finish!

It's appealing as a disincentive to cylinder antics
and has the additional virtue that it ensures adequate
energy for gate finishes since 500' gets most gliders
roughly to redline at 50' over the airport. Since the
main complaint about gate finishes is inadequate energy
for a pattern this basically forces a rolling finish
decision at 1 mile or more if you don't have the energy.

I'm assuming you don't get the penalty if you do a
rolling finish. I would also allow the CD some discretion
over penalties since 499' and 150 knots is not the
same as 499' at 40 knots.

Pretty interesting - I think this came up last year
didn't it?
