OpenRA

Can someone explain to me in detail how the hell this weapon works? Namely the falloff damage? I've been making a balance patch for the OpenRA version of this game, and this is the only thing left to tweak. I wanted to simply increase the range, but doing so causes it to misbehave, either it deals no damage at the beginning half of it's shot, or it does nothing at all and I suspect the falloff is what's causing it.

No answers yet? Can anyone help?

The original was
Falloff: 0, 0, 100, 0
Range: 0, 0c450, 4c0, 8c0

I did something like
Falloff: 100, 100, 50
Range: 0, 6c0, 11c0

and the range was improved
