Ya got me there, I do not know.
Good point. However, I was doing 0-60 testing before the hp testing and had practiced 1/4-mile launches so I was already familiar with the car. A slight burn-out gave me the best launch and lowest 1/4-mile time. For the hp testing this isn't required, you just gotta get moving.
Most of this sounds fine. I'd want to know more about the G-Tech just to know how sensitive it is to interpretation. Does it record a digitized record of the run so that you're not left to choose a max meter position? If so, one thing that might be wrong about this would be the fact that the test was not "Blind." Not being blind makes any test more likely to turn out the way the tester wants it to.
Another might be the fact that this car was rather new to you, and the synthetic runs were done after you had some practice. Most people will show some improvement with practice at things like this, especially if they get to look at the results each time.
How do you get from acceleration to HP?Hey, I'm not the one working in the physics dept! :-) Here's the product listing from their web site, my unit is the GTechPro which is no longer available: http://www.gtechpro.com/prod.html
