Dartfish does the same thing. Again, just a tool. Precise angle measurements don't mean much, because people aren't numbers. I always worry when folks get hung up on angles...
The best fitter I've ever met doesn't use any video system at all.
The best biomechanics researcher I've ever met doesn't use Dartfish or Retul. He uses a 60 fps camera with plain ol' video playback for most things, and something crazy fast like a 2,000 fps camera with plain ol' playback for real high-speed stuff. He doesn't measure angles from a 2D system (anything on a screen is 2D, it can't be avoided). He measures people instead.
I once drank the Dartfish/Retul Kool-Aid. Sexy computer tricks are impressive, but nothing substitutes for a good brain and a thorough exam of the rider's body OFF the bike.
Don't choose your fitter by what expensive toys they have. Ask other riders, ask sports med clinics, ask physical therapists; find out who they recommend.
If you can get a hold of Andy Pruitt's Complete Medical Guide for Cyclists, that's a good book to have handy. (take all the numbers with a grain of salt, of course)
