Does anyone know the "formulas" for the game?

By formulas, I mean the exact multipliers that each stat of each weapon or skill or ability has on the overall performance of a gladiator.

For example, how much health do you gain from an extra point in size, strength, or endurance?
How much does the possibility of hitting your opponent increase from an extra point in agility?

edit: I know that part of the game is in finding things out myself through trial and error, but its always nice to at least see a number-based overview of how each action I make affects my gladiator.
