Looks like Michigan might be needing that rumored 17th district event, as FiM is at 316 teams (the 16 current district events have a capacity for 320 teams).
Spreadsheet with details here. Other tidbits...
- FiM is still missing 20 veterans that competed in 2014. 8 of those were rookies in 2014. I expect at least of few of the missing teams are hidden on waitlists. The overall retention rate at the moment is 92.8%.
- Michigan currently has 58 rookies, 21% of all 2015 current rookies.
- About 160 Michigan teams are on waitlists for at least one event. This doesn't include missing teams, so the actual number is higher.
