You have to see how the female pole vaulter, Yelena Gadzhievna Isinbaeva does it & how she handles things.
In her case, see comes good at major Grand Prix meetings, and vaults 1cm higher, one big event at a time.

Bonus money. Not just from the meet, but more importantly, from his sponsors.
Look left, see the time, ease back. You're home with a new WR, yet more importantly, you leave yourself room for better times to come.
In reality, he screwed up by about 1 meter!
Bizarre to say, I know, but 9:68-ish would have been just fine.
Not so easy to do, this "just everso slightly edge the performance envelope" – easier to do it in the pole vault me thinks!
If you look back at all the 100m WR runs, it's taken about 100 years to knock 1 second off the World Record.
As long as he stays the right side of any doping and continues to grow he will be invincible beyond any other althelete in modern times. Something to really both savour and look forward to.
