It's hard to imagine that accuracy (of that relationship and any inferences you draw about it) won't be an issue for that, but who knows?
You brought PowerCal up to demonstrate that it's possible to predict power from HR, but you can predict tomorrow's lottery numbers from HR, too, if you don't care about accuracy.
No, I brought up PowerCal to demonstrate HR and power are related. We don’t know what the OP is thinking to do with the data informing that relaionship, so the questions of accuracy (presumably you mean in terms of HR correlating to PWR) are of irrelevant at this point. What Powercal has proven, however, is that it’s fairly accurate at calculating average power over the duration of a workout in particular and quite typical circumstances, even more so in controlled workout scenarios such as stationary training.
But again, the pros and cons of PowerCal are not the issue at hand.
