Bolt eyes 400m World Record

@Charlie_Francis

19.1e = 18.9h aprox, so the standard formula is 2 x 200m ht result plus 3.5sec.
18.9 + 18.9 + 3.5 = 41.3h = 41.44 to 41.54e!!
Still want to keep the exclamation points after 42.9?

Charlie is spot-on.

I’m going into tetanic contractions just thinking about 41.5 :eek:
