Yeah, I think we just have a different perspective of the same thing. I guess the only difference is I wouldn't really be thinking about the 3/4 part. It would be pretty amusing to see someone pull out a chart or calculator. I might do that the next time I play just to mess with the guys I'm playing with.
funny (but I bet you a dollar that a lot of the pros have detailed stats on which shots do what and some key points to each shot....)
my 3/4 is hands go back to about shoulders rather than full on
my 1/2 is hands to waist
if I practice it, I get pretty consistent carry distances - that part doesn't bother me at all - I like repeatability.
(However, one day, my range finder ran out of batteries (my depth perception is so lousy, I would laser my putts if it helped). I did GREAT near the greens. I had a bitc* of a time with my medium to long approaches. So I'm really a mixed type, with a serving of "it depends")
