First of all, did I ever say that Geb is a pose runner? All I said that his running very much ressembles Pose, means he runs Pose-like intuitively, means sometimes he eneters Pose-style running, sometimes he is out it, not knowing it, cuz he does pose-like things not knowing it. And for one pic with his straight rear knee I could find a dozen where he never straightens it. And being not a Pose runner per se he is out of his "intuitive Pose" especially in his final kick - your pic prove it. So what?
Concerning other runners in your pics - what does it prove? That fast runners push off? Did I ever argue about this? Hell, these runners could outrun you or me even if they chose to run backwards. Or do you think that if an elite has some flaw in their technique and still is able to run fast - this should mean that he runs fast DUE to this flaw? I guess you are arguing just for the sake of arguing.
