You will not get any detail other than what is in the Mobhack help files. (I'll assume you included the technical data in the mobhack help file under "checked the manual")
That is because the base code was SSI code, and the algorithms were not to be made public. Even if they were, these are not a simplistic formula like the D6 shift tables found in old cardboard-shuffling games. The combat code is dozens of functions, and thousands of lines of code.
The best way to play around with the values is to set up range-test scenarios (use specially-built targets which dont fire back, to avoid complications like eating a returned APDS round
!. You will need to run each scenario a statistically significant amount of times, tinker a value, run a few more times to see what happens, and so on.
