Im looking to create a ranking system for users on a gaming site.
The system should be based of a weighted win percentage with the weighted element being the number of games played.
For instance:
55 wins and 2 losses = 96% win percentage
1 win and 0 losses = 100% win percentage
The first record should rank higher because they have a higher number of wins.
I’m sure the math is super simple, I just can’t wrap my head around it. Can anyone help?
ELO is more thorough because it considers opponent strength when scoring a win or loss, but if opponents are randomly matched a simple and very effect approach is:
(Wins + constant * Average Win % of all players) / (Wins + Losses + constant)
so with 0 games the formula is the average for all players, as you increase the number of games played the formula converges on the actual record. The constant determines how quickly it does this and you can probably get away with choosing something between 5 and 20.
