First, welcome to BB-Edju and BB-Patrick
Our current estimate for what this formula will give us in 7 weeks is that it will mean about a 10-15 upward adjustment at the top.
I suspect our definitions of average might be fairly different. The average salary for a player in BuzzerBeater is currently 3342. This will not change very much.
Maybe just a suggestion. How about, when the allstar break comes closer, have a new player value. His "expected salary next season". This could be only visible by the team owner and when the player hits the TL. It would give every team a better idea of what is coming.
