HTC has modeled trajectory and velocity, yes.
Trajectory yes (gravity has a big effect.) But I wasn't sure if they modelled drag, or assumed the speed doesn't change much to matter over bullet range in game (1500 yds).
I'm wondering what the terminal velocity of a MG round in game is. I believe they disapear at 1500 yrds. What I wanted to further understand was how much the damage value of a MG round changes with distance. This would be a function of it's speed. From buster's Table I can calculate the Drag and hence the terminal velocity. From that I could calculate the drop in damage as a function of the drop in Speed.
This goes back to my original question which, I now assume to mean the damage and velocity change over time and distance travelled.
