Again,.... skate alignment is MUCH MORE complicated than cycling cleat alignment. On a bike, the foot travels through a circle and is always in contact with the surface through which the power is being transferred. So, alignments are subject to pretty rudimentary physical principles. Even still,... although I know you feel like you made substantial increases in power output with alignment changes, it's actually pretty atypical. The placebo effect is almost impossible to eliminate and I've seen just as many cases when riders power got worse due to a poor fit adjustment. The literature and even the physics themselves don't support the claim that substantial power improvements can be gained with most traditional biomechanical alignment changes (mitigation of soft tissue injury maybe,.. but power, not so much). There is no doubt that the order of improvement would come from 1) aerodynamics 2) gross changes that would optimize hip angle to maximize power output while maintaining aero position (this is an optimization problem),.... then..... way way way down the line would be like 10) cleat alignment. Granted, improvements to a simply horrible position or fit can yield improvements. In general though, performance improvements due to most biomechanical changes to a rider who is already a trained rider are very much oversold and, ... hence... snake oil 😉 My point with this rant is, the oft cited notion of "scientific" approach to bike fit using biomechanical tools to improve performance is mostly hogwash. **
OTOH, any other type of locomotion (e.g. running, skating, skiing, etc) is subject to many more degrees of freedom and, as such, it is much more difficult to get generally applicable rules that apply. So, the issue here is that there may be gains to be made due to the enormous degrees of freedom, but it's difficult to get away from the "whack a mole" scenario. I.e. if you make a change how do you know it doesn't have an unintended consequence that could be detrimental? All that being said, it's plausible that a sound biomechanical approach could identify issues that if rectified could result in improvements. There just isn't enough info right now to determine one way or the other. Simply using force plates to measure jumps and gross asymmetries isn't enough info imo. We shall see as more info comes out.
**I know this rant seems off topic, but Bunnyman alluded to the approaches used in cycling and I thought it would be good to point out some of the misconceptions regarding these approaches and how it could inform this topic.
