Hmm, how would you know how much lead you're putting on the clay if you can't see your bead/barrel? Most of the professional shooters I've watched on youtube still have their beads, digweeds got his high viz red on his perazzi. Even if you don't use the bead you're probably using the barrel to gauge lead. Mind you I'm talking about peripheral vision, not hard focusing on the bead and trying to line it up with the clay or you'd see two clays.
By the time that you have shot 25 straight at skeet , or 80% or better at sporting clays, it will make a lot more sense to you. When you have shot 100 straight at skeet or 90% at sporting clays, then feel free to start telling most other people how they should be shooting.
Had an interesting experience shooting trap on Sunday. A very monochromatic day, grey sky, black trees and white snow. For some reason that I haven't quite figured out yet, the orange clays were almost impossible to see. Because you couldn't focus on them they looked tiny and moved at light speed. We switched to white ones and, oddly enough, they slowed right down and looked as big as dinner plates. All because you could focus on them clearly.
That is exactly why I choose different lenses for my shooting glasses to match the lighting conditions.
