The actual correlations are as follows according to Bondarchuk. 11.4-11.7 100m time is .369, 11.1-11.4 is .354, 10.8-11.1 is .297, 10.5-10.8 is -.154, 10.2-10.5 is .178. As you can see these are not strong correlations but there seems to be something there for beginners. As the sprinter matures and times drop, slj becomes less relevant. The field tests that have the highest correlations to 100m speed are alternating bounds for distance over 20 and 50m. Remember, correlations are not cause and effect. Correlations simply indicate a relationship. Anecdotal evidence from my own stats over the years tend to show my best sprinters usually jump the farthest in all tests. I have not subjected this to statistical testing, just observation.
