you obviously don't understand my point here, yoda's force assisted speed is greater then kuns natural speed, one's natural strength is no comparison to anothers force assisted strength. Maybe Kun might also have force assisted speed, we haven't seen it as far as I know and there's no proof that he does (I'M NOT saying it's not true because we don't know about it merely that we shouldn't make assumptions either way) Now considering that it's extrmely probable that kun might have this ability, I personally beleive yoda has a deeper natural connection to the force then yoda, Including the amulets I'm not entirely sure but without the amulets to bolster kun's force connection yoda will just be that much faster then he is...
