What's the shot-origin variable? (Need to tweak it so 2 maps of mine work again).

The shot-origin seems to have been lowered recently. This causes redstarrepublic and other machinegun nests to be unusable for defense. I need to raise the shot origin to whatever it has always been in nexuiz for those maps. What is the svar for shot origin? Currently it shoots low, especially at short distances.
