i know there are a number of formulas that predict what a 60 will show for 100m.
there is the 60mx 2 the minus 3 seconds, or one that i found was a good number was just add 3.60 to the 60m time
so the x2-3 seconds gives him 6.60x2=13.2..- 3 seconds = 10.2
or add 3.60 = 10.2
you shouldnt use someones 60m in route to outdoor PR as this is at the end of the season, but you use CURRENT 60m time of indoor to predict what they might be able to do a 100m at current fitness.
terrence jones is the leader right now at 6.45 so lets try that out
9.9 with the 2x-3 seconds, and 10.05 with adding 3.60 seconds
rikkoi brathwaite has a 6.54 currently
10.08 with the 2x-3 seconds, and 10.14 with adding 3.60
his 100m pr from last year was 10.10w (3.2).
so maybe best is get the two projected times and then average them
boiling then = still 10.2
terrence = 9.975
rikkoi = 10.11
lets look at jocobs 6.47 then a 9.80 at the olympics
2x-3 seconds gave him a 9.94 and 10.07, average 10.005 so he was able to drop .20 by the end of the season
this gives
boiling = 10.00
terrence = 9.77
rikkoi = 9.91
of course this doenst consider speed maintenance as some guys rip a good 60 but flail with form and deceleration and run 10.00-10.10 with fast 60s. but it will be interesting to keep an eye on this terrence guy once outdoor starts
