Beagle,
Two things strike me here, firstly you are dealing with BOTH distance off track, AND drift - using double TE or TE + CA just uses the angles.
The second point is that if you are teaching this to students they NEED to understand it - it is fine saying turn 40 degrees, but then they convert to a much faster aircraft ( a twin maybe?) and the figures change. I do know this technique and did so before the seminar, I just found it more involved than needed for PPL nav.
At the end of the day the thing that matters is it works for you and your students, I have tried both and found what works best for me and those I teach, I think we will just have to differ on this one.
