What sort of RPM drop do you get when you pull the carb heat in
cruise? When are you applying carb heat? How long was the power-off
glide? What were the temp and dewpoint on the day in question?

In cruise, I see maybe 50 RPM drop. I've always applied carb heat on
downwind before I reduce power from cruise (2150 RPM) to about 1700 RPM
until on final, then to about 1200 RPM about until I roundout for the
flare. If I recall, the temp/dewpoint yesterday morning was 16/12C, so
the air probably did have a fairly high moisture content.
