Let's say I wanted to count the ten as -2 and the jack, queen, and king as -4. If I ran a simulation with them all counted as -3.5 how much penalty should I subtract to approximate the way I'm actually counting the tens? What if I ran a sim with the red tens as -3 and the black tens as -4? Is there a way to figure this out or could someone give me a ballpark guess as to how much percent to reduce the WinRate and Score?

Thanks for any help.
