Very controversial words from Oscar after about how ridiculous it was that Oliveira was able come from the back and overtake him and that it was all down to increasing the length of the blades and shouldn't be allowed.
Coming from 8 meters behind to pass a guy running at ~23mph, and doing it in <100m means he was gaining gained a meter on him for every ~13 they ran. That's pretty hard to put down to athletic performance, it looks like (as was feared) the paralympic running is now simply who has the best prosthetics.
They said they've measured all the blades and they are fine, though on looking at them they did look like they were quite long (longer than if he had his own lower legs). But really you can't probably tell much just by eye.
To be honest, saying they conform to regulations doesn't really mean much when the regulations have never been pushed like this, in F1 the regulations have changed a lot over the years due to technological advances.

If I decided to take up MMA I would be at a distinct physical disadvantage due to my disability however if I turned up with my prosthetic arm wrapped in barb wire and hooked up to a taser nobody (sane) would have the guts to fight me.
If an athlete with a prosthetic is getting such an advantage from it that he can perform better than he would be able to without a disability that's not really an issue (for the paralympics anyway), as long as they all have the same advantage. We are now in the realm that prosthetics have advanced so much that they offer a distinct advantage over their biological counterparts.
TLDR/Conclusion: I think all the prosthetics for a set event/race should be made by the same prosthetic company and be of the same model/design, and be correctly sized for the athelete like an everyday prosthetic (not just conform to some set sizes but be correct for the man) thus negating and artificial advantage a competitor can have over another.
