Very good ideas. Hope they make to their list.
ad 1: appreciated
ad 2: Any competitions have common green speeds for all competitors - choose or let the game select.
ad 3: Would like that, too. Alternatively, members may fill some spots without playing.
Concerning the green speeds, we recently set up part of our CC Championship as follows:
Three parallel tourneys on the same course for separate tier clusters, each with a different green speed. Thus each tier would play at or close to their habitual green speed:
A) Tour Legends, Legends, on Tournament (12) greens
B) Tour Master, Master, Tour Pros on Very Fast (10) greens
C) Pros, Amateurs, Hacks on Standard (8) greens.
The final round would be common for all, on Tournament greens.
