Back at the US Olympic trials in 2012, Beach was I'm pretty sure 3:05 at the bell in the 1500, definitely no slower than 3:06. Dude would have CRUSHED the decathlon 1500 World Best (3:58.7) if he hadn't been so selfless and pulled up in the home straight for Eaton.
I don't know but Seb Coe ran 1:41 off 46xx second speed dropping to 1:47 is not very impressive. Actually his 46.72 off 10.52 is also a poor conversion. He needs to concentrate on one distance I would say that should be 400m
