40 yard times

Track & Field

I’m looking for info on the 40 yard.
So much “stuff” spread on the internet and finding times seems impossible.

From what i have seen - 4.25 seems about the fastest reliable time?

Also - what is the current best method of testing -
Ie, surface,
shoes,
start (blocks, 3 point, standing etc??)
and start (gun, clap, go when ready?)
And timing - stop watch, lazer, electric of what sort?
Timer - off reaction? off 1st movement? something else?

Cheers guys

I think standard conditions would be hand-timed off first movement from 3pt start on artificial turf.

What’s the equivalent of artificial turf? There is none where i live - or if there is, i’ve never seen any so i have no idea what it’s like to run on.

Most places don’t have artificial turf these days, field turf is the new thing.

shoes, depends on the sport.
start 3pt
and start first movement
And timing - stop watch or touch pad
Timer first movement
