Just downloaded one of the newer versions of Golden Cheetah, really cool stuff. Especially the "metrics" section. If anyone here works on it, thank you very much for your continued dedication to this project.

On another note, what is the deal with a negative aerobic decoupling measurement? Does that mean that average heart rate at the same power decreased in the second half of the ride? I've only seen these on really easy rides, so it is probably meaningless.
