I am certainly not an expert at reading the wind. I can do complicated math but I don't put much stock in ballistics calcs. To many unaccounted for variables. If I want to know what the wind/mirage is going to do to a shot I shoot the sighter target. One way to beat the wind for groups is shoot fast before the condition can change. Shooting for score that is too hard for me, I can't change targets fast enough to get a whole string run in one condition.
I have never had luck holding off to compensate for the windage. I will use the windage adjustments on my scope. I want to keep the same POA as it is precise either a dot or cross. Maybe with something other than a fine crosshair you can use the windage marks on the reticle.
