Cause wind has much more effect on impact than spin drift. And if your zeroed at 5 on some windless day?? you have any spin drift compensated for with the zero.
Now you still have to call the wind, when it appears...which it will.
If you watch the mirage move through a spotting scope, even at 200 yrds with a mild 5-7 mph wind, full value or other wise, you`ll forget about spin drift.
Fun and interesting to talk about, but IME, application gets lost in the wind....or is it "Gone with the Wind"?
YMMV
