Popov's 1958 marathon time 

I am really puzzled by what happened at Marathon world record progression. I removed a note (diff) and you seemed to revert me (diff) with a comment suggesting it was a simple "undo" (Undid revision 452672700 by Thincat (talk)) but in fact your edit corrected the extended time. Your edit was better than mine. But what actually happened? Seeing  what I took to be a reversion I studied the matter further and found the corracted time to edit it in. However my second edit (as it turns out identical to yours) seems not to have been recorded. Weird. Did you in fact correct the time in making your undo?
