I think your question will answer itself as you attend the course. You'll learn a lot that is applicable to skiing, and if it applies to skiing, it applies to teaching! In particular, it will help you identify what movements and errors may be equipment-related, vs. just technique-related. And it will help you advise students when they may benefit from an alignment/boot specialist.
I have not actually attended a "Masterfit University" camp, but I have worked a fair bit with Bob Gleason, who is the training director/chief instructor (or something like that). He has lectured for PSIA trainers several times in the past few seasons (very informative and entertaining), and has participated in alignment clinics as well. He is well-tuned to the idea that you have to observe the skier actually skiing, in addition to the measurements taken in the "lab," to arrive at the optimal alignment/canting/footbed/fit solution. He likes to to work in conjunction with instructors--he does the measurements and initial adjustments, and the instructor then takes the person out on the snow for a few "test runs." Then they report back and refine....
I've even seen Bob Gleason arrive at contradictory solutions based on lab measurements vs. skiing observations. In these cases, he usually goes with the skiing! Then he goes back to see what he might have missed in the lab.
Anyway, the point is that Bob Gleason and Masterfit U. are pretty savvy when it comes to instruction and the real world of skiing. I don't think they'll lead you astray.
Have fun. Ask questions. Report back!
