The reason for the 1000 questions is because I've seen two specialist bike fit physios already; and there was a lot of stuff I felt wasn't covered. They also contradicted each other on several issues.
no surprises there. bike fitting is not a science, but more an art, based on experience (and some science / physiology) - just ask steve hogg. anyway,
now in messy point form.
- measuring hip assymetry is subjective. so many factors can make you pelvis seem uneven - and they're rarely pelvic.
- tibial and fibula length - just one will do, but we'll call it lower leg length, as its typically from knee joint line to that bump on the outside of your ankle.
- torsional assymetry - do your feet point at at the same angle.
- sub talar joint range - no idea why you'd care about this and i doubt anyone could measure it in a meaningful way.
- hard to measure degenerative disease except via post mortem
- forefoot valgus/varus. again, meaningful measurement is hard to attain. often rearfoot valgus is used for normal people, but us cyclists tend to be more 'on our toes' .
you'd never bother with an xray to measure any of this. whilst i can understand where youre coming from with your AKA, you might be looking into this just a little too deeply.
met domes are good, maybe even orthotics for the mid foot - though there's no need to worry with the heel that much.
and speedplay pedals - then you can shim / wedge / change axle length and have all the ankle float you need to be in more control of your lower limb cycling biomechanics...
Any insight would be much appreciated!
