Tilt, come to the Training arena and practice some with the Lead Computing Gunsight (LCG) on. Just ask around, you usually will find willing targets. The LCG will show you the amount of lead needed.... try to use it to memorizes the gunsight picture for different situations (angles/speeds)
Also, if you have continued issues with missing "shots that shouldve been dead on target" - check your internet connect. When i have "those nights", i usually have a flaky connection (no downright warps, just everything being off somehow).
