Paul, would it be possible to just check to see if a specific weapon has acc > 100%? Any that does could just not have its hits and shots added, so glitched accs wouldn't be very problematic. What about conditionals for stopping divide by 0s?

Thanks for fixing up my formula giriel, I had forgotten time with Damage Received. I don't see what the 3600 is for, not all maps have that play length, but I guess I am just missing something, I don't know a whole lot about the system.

"we should increase the reward for using the proclaimed "skillful" weapons. "
Agreed. I had 400 damage with a panzer where I could only get an HP bars worth from smg; even with a 100% hs ratio, the panzer would get a better rate. Even doubling the headshot ratio bonus would leave the panzer with a large advantage, not even including the fact that the panzer is more accurate. There definitely needs to be either a much much larger headshot bonus or giving an alteration to the damage of specific weapons.
Altering the headshot bonus too much gives emphasis to only getting headshots, even if it means being extremely inaccurate and therefore not even doing much killing, although I guess multiplying it by damage helps with that. If I get time I'll try recording some stats and doing some tests, but I haven't had time in a long time.
I don't think damage can even be calculated separately for different weapons, and trying to alter it there would be complex and problematic. We will probably have to beef up the headshot ratio area.

Sorry I've forgotten this for a while.
