Rusty, do you throttle back to = idle in the=20 pattern, base, final?  My idle is around 1200-1500, but I seldom=20 ever go below 2500rpm on final in flight.  If may be that if = you=20 establish you minimum rpm as you are stabilized on final, then the = drag=20 factor is there and you are already compensating for it.  If you = are=20 stabilized on final and then drag it back to idle is when I find the=20 effect. 
 
Hi Ed,
 
I'm almost always at idle during the entire = final. =20 What I can't say is what my rpm really is during final, because I've = never=20 looked at it that I can recall.  I'm sure the airspeed raises it = some from=20 the 1600 that it would be on the ground, so maybe it is = 2500.  I=20 should also add that I often don't use flaps.  When I do, I = usually=20 only use about half.  Full flaps, slow airspeed, and idle power=20 will truly plummet.
