It's completely deranged that in a sport like running, you wouldn't care about your form, or think it had any bearing at all on performance.
That's not to say there is one perfect form for all, but that's also not to say that form can't be improved for some individuals.
That's also not to say that you can simply change your form. Often you have to work on weaknesses to let form change naturally.
What's completely deranged is to think you can draw inferences out of thin air as to what constitutes proper running form and improve it by providing arbitrary cues that are not in any way anchored to known scientific facts.
Identifying perfect form is impossible. That' s not to say that you cannot pick out some bits which are not beneficial e.g. foot strike a long way in front of COM - well that's clearly applying a breaking force so not good. Physics plays a major part in biomechanics. The challenge we have is in the fact we are living organisms - through repeated practice people can get very economical at a fundamentally inefficient movement, so is the end output going to be worth making the change.
