pardon my ignorance… but I have no idea what you just said to me 
It doesn’t mean your in 10.5 shape… it means you could have run next to me for 40m back then… thats it! READ MY LAST POST ABOUT MY TRAINING PARTNER WHO RAN 10.6 but had a crazy 30m.
Just incase you want another example I know a guy who started runnin track in april 2006 and by june he ran 10.62… so you’d be thinking WOW… he’s gona run 10.0 nxt year with training… well the next year he ran 10.56… it’s been 3years and he’s only run 10.27 which is all well and good but it’s still far from running sub 10 and a hell of a way behind the likes of Asafa and Usain… Go on Youtube and watch Asafa’s world record at gateshead… look and dwain and frater… they are down the road and thats 10.0… look at Harry AA he ran 10.3x… PLEASE DON’T INSULT THE SPORT I LOVE!!!
another perfect example is your national hero… Yepishin… 6.52s 60m but 10.10 100m? or the guy you mentioned who runs 6.58 but runs 10.27… Wallace Spearmon can only run 6.72…? 6.6 high on a perfect day… 9.96 100m!
