To be fair, in the pole vault most world record tries occurred after Bubka had clinched the win and the bar was raised to the next centimeter above the current world record. So of course the record was always broken by the smallest legal margin.
If Mondo had gone after the world record at the European Championships the bar would have gone from 6meter05 to 6meter17 (one cm above the current record of 6m16).
(and Mondo should have gone for it, one of his jumps looked good enough to have cleared it)
(conversely, Lavillenie was a moron to go after 6m21 after clearing 6m16 and breaking the old world record of 6m15 in Donetsk. He ended up flubbing the jump and injuring himself and getting knocked out of worlds)
Back in the 1970s a soviet weight lifter did the same thing, breaking the world record by the smallest amount to maximize the number of bonuses he cashed. Vasilly Alexiev? Maybe the biggest steroid doper of all time.
