For those of you using handheld GPS's when you fly IFR:

Do you use the throttle to increase/decrease power to match the ground
speed to the approach speed table so the time is correct to the MAP?

A buddy of mine does this. Drives me nuts. He'll sit and screw with
the throttle to get 90 knots ground speed. I want to reach over there
and smack him upside the head. He makes himself so busy trying to fly a
certain groundspeed and he can't see that.
