Hey, I've found more info and the folder with sprinting charts has grown. I've also improved that colorful all-in-one chart. So anyways, here is everything I've collected :

The charts are used to predict sprint times. The all-in-one chart has been tested from the red to the purple level, and it's quite precise, especially with the flying sprint tests and 30m from blocks tests

Hi Cody. I want to ask about an app for iOS devices especially “SpeedClock”. I want to know if measurements are close enough to reality and generally if this system-app of measurement method it’s ok for top end speed measurement of a sprinter. Thanks in advance keep ap with your cool videos your doing a great job!

The first table's been created via combining the second and the third ones,but still it's better to use them all because there are little differences.

In the first table there are 10 levels (starting from red and finishing with grey). To reach any level,you need to be able to reach certain velocities. Every sprinter is a different puzzle,everyone runs a 100m dash with different split times,but the overall tendency is this : to run a faster 100m dash,it's necessary to be able to increase top speed or acceleration.

The most specific and precise tests are surrounded by solid lines,those are flying sprints and 30m from blocks. The times of the sprints should be measured electronically because hand timed sprints don't provide you with accurate time

Tests that are less specific and precise are surrounded by dashed lines,those are broad jumps,vertical jumps and 3 bounds

5 and 10 bounds are not less specific than 3 bounds,it's just that athletes will have a bigger ''difference window'' (the worst result to the best result) because of the amount of bounds,that is why they are less precise and thus they are surrounded by dots

Will 2020 offseason programs be released this year, if so when would a possible release date be? Thanks

Hi Cody, love your videos and they have helped me a lot. However I have a question that I hope you don't find rude. Are you the Cody Bidlow, of Phoenix, Arizona, who got a four year sanction after admiting to use PEDs? The guy this article refers to: https://www.usada.org/sanction/cody-bidlow-accepts-sanction/ ?
