Or "length."

That has been my evolution, too. The FFP guys talk about how fast they can read their reticle and send a held-off shot. Well, there is nothing faster than simply using your target as the scale and pushing over "two PD widths," or "three PD lengths," etc. People worrying about how inexact that is must not have shot in the prairie wind much, because it varies wildly over 300 yds or more, and you don't even have wind-flags out. Your only real hope in a good wind is to shoot, see where you hit and instantly correct and shoot again, before the wind changes again. SFP/FFP makes ZERO difference.
At first I wanted to learn how to measure the wind and then hold over the exact amount of MOA to put me on the target. But once I got that down I moved on to simply using my target as the yardstick. Not all PDs are the same size, of course, and you have to be able to tell the young ones (adolescents) from the adults, but that can be done well enough with practice.
You know, if NF put the MOAR-T reticle in any FFP scope maybe I'd get one, "just in case." But they don't, so it is SFP for me. But since I am getting so much better at just "Kentucky-ing" the squirrels (hence my name), it really doesn't matter. The really, really important thing is having a platform you can see your strikes with. Even using the rat as the scale, I still usually look down and see which hashmark I am on. Then, if I miss, I see which one I should have been on. It does not matter whether it is minutes or mils or FFP/SFP or what the power is set on -- if I held over 4 lines and the bullet hit at 6, I know what I need to do.
But I also note that I held over 2 PD lengths, when I should have held 2-1/2, and I log that away for future reference.
