I have changed some courts. I've put clay slower and grass quicker. (I've increased net influence on grass and increased some malus on clay) But results at the end are not realistic : Muster can reach Wimbledon final and Sampras win 5 french open in a row...
I lowered and added a few topspin to players...got more realisitic results I changed clay to -3.0 and changed grass to 3.0 changed blue green cement to 1.0
Venus dominates Wimbledon now..made QF or better in each apperance won three times Serena won 3 of 4 slams in 2002 ill give u more results later
