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
