During Kellerman's WC Testimony, he also describes the JFK Limo's rapid acceleration as, "jumping out of the GD street". Of course, we do Not see anything close to this level of JFK Limo acceleration on the Current Zapruder Film. Basing conclusions on what we see on the Current Zapruder Film will frequently lead to inaccuracy, which is the intended purpose. This frequent inaccuracy also applies to the speed of the JFk Limo being based on frames/images from the Current Zapruder Film.
