Yeah, again not looking for something perfect... if I did, I'd by a power meter. Looking for something to give me a "feel" for the power I'm putting out. Don't care if it's "real" as long as in the big scheme of things it all averages out. I can easily enter height, weight, age, sex, speed, cadence, etc. into a computer program and come up with a guesstament. That's all I'm looking for. So, going back to the original question, do you know of a computer that does this? If not, then no need to answer. Calso, your answer, "I don't know of any computer that does that" quite sufficient!
