I'm starting a league in January and I'm trying to finalize all the details. I've been searching and searching for the best scoring system for our league. I think below seems like a pretty fair calculation, our game can vary between 8-20 players on any given night.

10*(SQRT(number of players/place of finish))

Our league will have varying games (All no limit holdem) but sometimes rebuys sometimes not, sometimes bounties sometimes not...

I would like to deduct points for any player that rebuys/add-ons in a tourney (when we have rebuy tourneys its unlimited rebuys/add-ons for a set period, usually 3 rounds), but using the above formula I'm not sure the best way to incorporate point deductions for rebuys/add-ons?

Then, I was curious to peoples thoughts for bounty tourneys, there will only be a handfull of these. For all-non bounty tourneys I don't want to reward people for knocking a player out, but wasn't sure about adding points for knocking players out for just bounty tourneys?

Lastly (I think), how would I write the formula for TD3 for each of these 3 scenarios; by itself, with losing points for rebuy/add-ons, and with gaining points for knock-outs (incase we choose to go this route for bounty tournies).

Thanks. And please give any additional input that you think would help. For example, I'm not really interested in making point calculations higher for higher buyins, our game is a constant buy-in except that bounty tournies are $5 more for bounty's, and the last tourney of the year is slightly higher stakes. Just want to make it as fair as possible since we may not have the same number of players for every game. I like the fact that you should get roughly the same points for making it through say 75% of the field in a 8 person tourney as you would in a 20 person tourney, but the winners of a larger tourney get more points than the winners of a smaller tourney as it is more dificult to beat out more players.
