Alosaurus,
The 3-4nm/1000' was a ball park calculation at max l/d (clean)speed, or if you prefer, green dot speed. Please don't confuse it with a normal ILS where you already have slats/flaps extended to some degree.
But the main thing I was trying to pass on was the "pitch for aimpoint, gear/flap to control speed" concept.
In any case, hope I never have to use it for real.
