When testing you should also record air quality
This hasn't been talked about recently so I thought I would mention it again.
In order to compare test results across different days you have to also record the air density. Recording temperature isn't good enough. There can easily be a 50 to 75 rpm difference from day to day even if the temperatures are similar.
Or if you test in the evenings on the same day, as the temps fall usually the air quaility will go up and you will go faster because of it.
Watcon sells a RAD gauge.
Or you can use this website to calculate air denisity

Darn good idea, Phillip. Not for bragging rights or defending your position, but for datalogging. Everyone should do this.

That usually describes pollution content. I know where you are going, but lets not change the terminology or folks won't test on high-pollution advisory days.

yes yes I should have air density
higher density = more HP!

Well, he did say "air density" in the body of the post!
