Regarding the difficulty of sequencing gliders for landing after a
cylinder finish, this is exactly what gliders do every good soaring
day. All the gliders arrive from all directions at about pattern
altitude, do some sort of pattern entry, then land. Sometimes a bunch
of gliders all do this at the same time. We practice this all the
time, not just in contest flying. So at least this form of finish gets
practiced all the time.
