I hear you there, but be honest with me. Have you ever dropped a soft battery in your car and noticed a difference, not in consistency but in the times, maybe you are down a tenth or two. That is how I used to decide when I needed new batteries or had to tool on the motor some more. But yes, setup is just as important as the motor and batteries, actually more important as without the proper setup you are not going to get the maximum out of the motor. And I do think a lot of people setup their cars wrong, especially in high bite situations. At least from what I have seen.
