Trajectory validation as it's commonly thought of usually involves adjusting MV or BC to get the predicted trajectory to match actual. Sometimes MV and BC might be the correct variables to alter, but in my experience, often times the culprit is scope adjustment.
Example; A program predicts 30 MOA of drop. You dial it, hit high, and go about modifying MV or BC in the program until predicted matches observed. But did you ever check to verify that your scope is moving as you think? Correcting a trajectory based on MV or BC when the real problem is scope adjustment gives you the illusion that you're solving the problem, but what you end up with is a solution that's really
only correct for a single range. If you address the real problem, you'll have a solution that's more accurate for all ranges.
Shooter has a variable called correction factor, which is a multiplier you can apply to your sight adjustment so that the program accounts for the error between expected and actual reticule movement.
