Dont forget these are “loose guidlines” Some athletes might do great in some tests and not good in others. The best thing to do IMO is to take the tests and analyze where can you improve. For example some sprinters might have a good score in the SLJ and the 30m but might suck at the 60 and 150m tests. Here you would know that there is a SE issue and set up training accordingly.
hand timing in its self is quite a vague thing. I mean some people time from the first reaction to the finish touch. Others time from the go they shout out and then deduct 0.09 for a 30m (0.09 is the time it takes for the go to travel from the finish line where the timer is, to the start of the athlete on a 30m ) Some use first step timing and so on. I don’t know which is to be used. But for me. I once timed a training partner for his 30 blocks while being electronically timed at the same time. and the times on my stopwatch were. 3.67, 3.80, 3.92. Electronically the same 3 runs were as previously order. 4.22, 4.22, 4.22!!! SEE
i agree about the FAT times fast11, so then at the end of the day the variances in timed runs would be most likely from the person timing than from the guy doing the actual running!
i beleive the only way one can do it is through self progression, so if my coach is timing me in 3.6s and i drop it down to like 3.4s, another person with their coach might experience the same drop ex from 3.8 to 3.6 and yet both of us would settle with a 4.1FAT?!?
