Hello Perry. Love your work on perceived velocity. Do you have a recommendation for a training program for hitters specifically related to timing?
I was not able to view all of the presentations and yours was one that I missed, unfortunately. If you send me your PowerPoint, I am happy to look at it and send you any thoughts that may help direct you. The data that was given to the contestants was a little difficult to be specific. The EV Tunnel is defined very differently than that of the data presented. Also, virtually every pitcher has a different approach and success rate versus lefty hitters than righty hitters. The data was shown without differentiating, at least that’s what I was told.
Pitch by Pitch sequencing analysis is the only true way to measure EV efficient sequences, so you are on the right track there. This type of analysis will lead to a true sense of the atmosphere that hard contact happens. The rule is basically 50/20/20/10 when it comes to hard hit ball breakdowns. about 50% of MLB hard hit balls are within 6 EvMPH of the previous pitch. Approximately 20% are thrown into the Hitters’ Attention Zone (the speed range hitters are most geared to), another 20% of hard contact happens on pitches without an Ev Tunnel. The 10% of hard contact happens on EV efficient sequences. This varies a few percentage points either direction, for example the 40 longest HR study that I did turned out that over 60% were thrown within 6 EvMPH of the previous pitch and only 9% were on EV efficient sequences, or earned by the hitter when the pitcher utilizes his EV Tunnels and keeps 6 EvMPH between, as the Downright Filthy Pitching books describe.
Thanks for your participation and continued interest, hope this helps.
Thank you Michael, but please note that it is Effective Velocity, rather than Perceived velocity. Perceived velocity is the speed the hitter perceives the pitch to be thrown at…….and we really can only know that after the pitch has been thrown and the hitter reacts to it. We can judge, very precisely in fact, how early or late the hitter is in MPH’s.
The Time Training Hitting Programs, Level 1, 2 and the Advanced Time Training, are designed to introduce hitters to the world of swing efficiency, pitch recognition & timing as well as understanding game planning at the advanced levels. The programs come in hard copies and online video courses, except the Advanced Time Training is only available at this time in the online course, no hard copy.
Effective Velocity is the true reactionary speed of a pitch based on the location adjusted speed of the pitch. For a hitter to create his or her maximum exit velocity (the other EV introduced by this science), they must contact the ball in only the perfect 100% on time contact point and there is only one point for each pitch location. The pitch can be hit at various other points, but not at 100% swing efficiency and timing. The exit velocity will always show this to be true when tested.
Perceived velocity is possible to judge fairly accurately, but only after the hitter reacts to the pitch. For example, if the hitter brings their hands in and bends the lead arm to get the barrel closer to their body, they will have been quite a bit late to the pitch. So if the pitch was thrown at 90 MPH and it was located up and inside at 95 EvMPH, to hit the ball at 100% on time with 100% efficiency, they would not have drawn their hands in towards the body. From a side view, we can plot the exact 100% on time contact point and when it should the barrel needed to be there to be 100/100 – 100% on time with 100% swing efficiency. The hitter drawing their hands in would be both late to perfect timing and less than 100% efficient with the swing. The hitter ‘Perceived’ the ball to be much slower than it actually was.
Effective Velocity is the patented metric for converting radar or other speed measurement devices, then converting that speed into the true reactionary speed of the pitch.
