How do you set up a bowling league schedule for twenty eight teams playing 22 weeks?

There are a lot of ways, here are two: 1. Week number 1 is a fun week (nothing counts), weeks 2-7 regular 12 team schedule; week 8 is a position round; weeks 9-13 continue regular schedule; week 14 position week; weeks 15-19 are regular; week 20 another position round; weeks 21-26 regular; week 27 position and week 28 another fun night (and usually party/payoffs). OR 2. Weeks 1-6 regular; week 7 position; weeks 8-12 regular; weeks 13 and 14 both position weeks; weeks 15-19 regular; week 20 position; weeks 21-26 regular; and weeks 27 and 28 position. I hope that makes sense...
