Rusty, do you throttle back to idle in the pattern, base, final? My idle is around 1200-1500, but I seldom ever go below 2500rpm on final in flight. If may be that if you establish you minimum rpm as you are stabilized on final, then the drag factor is there and you are already compensating for it. If you are stabilized on final and then drag it back to idle is when I find the effect.

That makes sense to me, Ed, and it might also have been a factor in my prop strike incident.

You would think a bigger disc area would give more drag, so it makes sense, though I never noticed anything like that when I went from 68 to 74. Then again, my idle is about 1600 rpm, so maybe not slow enough to matter.

John, Clark said to stop messing up his prop. Yeah, I told him :-)
