The math behind performing all the observability tests is widely understood. It's not complicated once you know what you're getting into, but if you're looking at it for the first time it can be overwhelming. The observer is key to getting good results. Without that, your data will be so noisy as to be totally inconclusive.

Even better, I got to verify against a dynamometer at the Grand Prix racetrack at Spa-Francorchamps. And they said I can come back and put the roadster on the race track once spring comes. "For scientific purposes".

To tell the truth, the dynamometer was kind of scary. It took a long time (around 1 hour) to get a very dense data grid. Since this was my personal car, if something blows up it's not my research budget that pays! But it was a lot of fun, and we'll definitely be going back with some other cars where I've installed the logging unit.

Oh, I believe it! Thanks a lot for fixing it for me. And I'm guessing that I'll get to 5 pretty quickly, anyway.
