For the first calculation, if you think he should not have started moving his arm when his opponent’s knee was already approaching his eye (based on the pixel scaling I measured), then at what point do you think he should have started moving instead? I’m just curious.
In the first feat, there is no evidence that Gamin moved his arm while the guy's knee was that close to Gamin's eye.
In the second feat, there is nothing showing that the guy was moving in slow motion.
