I received the missing people and the positions, and I'm working it into the spreadsheets. I should have an update to the application this weekend.
I can set up the filtering in various ways, and was thinking:
By Seed (Range from 1 to 800)
By IFPA Ranking (Range from 1 to 40000)
Another Seed filter, grouping by 50 (i.e. 1-50, 51-100, etc.)
Another IFPA Ranking filter, splitting into equal 10% "bins"
If there are other ideas, please let me know.
