My distances are about the same as yours. "Driver unknown" is especially accurate! I use the driver frequently but I'd say my distance with it is anywhere from 200 or less to 260, at absolute best. I've shot 260 yards twice that I know of, where I could get a good measure of it.

I don't carry a 3 or 4 iron, but my 3h goes 180-190 when I connect. Also there's some difference with the wedges. My gap wedge goes 80-90, SW about 60-70, and LW about 50.
