All maneuvers are wind corrected, except directly before the pivot of the hammerhead, and the autorotation of a spin, must be corrected on the downline.
The points of the Sharks tooth, both normal and reverse, and the top of a humpty bump have a smaller radii than the entrance and exit radii.
Roll points are shown on the aresti symbols, usually in the center of the line, except in the case of the immelman which is perfromed at the end
of the half loop. Wind correction is correcting for track, not attitude of aircraft. I always thought that non aresti aerobatics are performed
in the Freestyle class.
As for wind speed, when I flew Pattern we just used the ruling of the FAI, and Masters pilots, if they don't want to fly you definitely don't.
