Forget to mention that the record presented is just for SHORT COURSE 50m freestyle in 25m pools, while the REAL 50m LONG course WORLD RECORD in 50m official Olympic Pools still belongs since 2009 to the Brazilian Cesar CIELO, broken the LONG course WORLD RECORD at Dec 18, 2009 in São Paulo CDBA Championship, and since them has NOT been broken anymore by anyone... THAT is the REAL 50m RECORD still to be BROKEN !
Honestly I don't mean to be rude but I think the messiness is probably just due to it being a fairly new discipline so the quality isn't really there yet.
