We have a couple derby's down here on Ohio waters of Erie, payback is dependent on number of entries, both derbies have a entry cut off so everyone knows at the cut off date what everyone is fishing for as far as prizes go and prizes are posted. The spring one does allow for one day 10.00 entries, spring derby is 50 a person, fall is 25.00 per person. The last two that were run paid a 10K grand prize.
Rosters are posted for both derbies and leaderboards are updated daily or close to daily.
I have no dog in this thread but participant lists (entries) and payback schedule should be posted, transparency is important with all events that require an entry and have paid spots to the participants.
