5/10/20 rule - when does it change?

[ANDREWLEVITAN]

Hello: I am in a league that has the 5/10/20 rule for free agency. I have never seen this before and didn't even know it existed......when does the 5% off for dropping players go to 10% off and then to 20% off?

THanks!

games 1-41: 5%, games 42-80: 10%, games 81+: 20%
