Hmmm. My brain is at capacity for the day and I'm not entirely sure how that differs from typical snake draft rules. Gimme 4, that feels about right.
Edit: Just reread. 4 is fine.
If ten participants:
1, 20, 21, 40, 41, 60, 61, 80, 81, 100, 101, 120
10, 11, 29, 30, 49, 50, 69, 70, 89, 90, 109, 110
That's how
Makes the later you go for the star picks give you a better average draft order than whoever goes before you.
