Everyone sees "lead" differently because of variations in swing speed. If you shoot a swing through method you might not see any lead because it is already built into the swing.
Good point Claybuster. I'd have to agree with that.
I should have qualified what I said earlier with the fact that I shoot skeet using a sustained lead. All though there are times when I do use swing thru when I get beaten by a high 2 or a low 6. In those cases I don't really see a lead either....it all happens so fast...when I see my barrels clear the target, the trigger is pulled. So no....in that split second I can't see a lead really on those targets either. Hell....even when they don't beat me and I do "sustain lead" them, it's for such a short period of time, it's next to impossible to gauge a distance between the barrels and the target.
What I described earlier is most applicable to the other targets on the field where you have more time to "gauge" the distances....or space between target and barrels.
