Seems to me that BlueLine has it - set yourself reference points starting from the threshold at XX kts, work your way back up the approach path you want and set intermediate aim points on the way.
For example, we teach (in C152s) 60 kts over the threshold with full flap, so we need to set ourselves up before then.
The 1 mile final at 500' works for us, and we have a target speed for that point, which is 65kts with 20deg flap.
Working back along the approach gives 70kts, 10deg flap just before you turn base. To set this up so that you turn base at about 45deg to your aim point, you need to start slowing down at 30deg to your aim point.
Power settings are incidental to achieving these targets, so we use whatever we need to LOOKING OUTSIDE! We start with a reference power setting of about 1700 RPM, but the only instrument we look at is the ASI. Heights are visual, looking at the shape of the runway and how that changes is the more important part in the initial training. As we travel to different aerodromes in the cross countries, then we start introducing more instruments but initially we want to get them looking outside.
Safe flying
