Allow custom calorie conversion

Thanks. Yes, I was hoping to have some sort of option not to export the calculated calories in the TCX file, and just let my analysis platform do the conversion using their native methodology. That seemed the easiest, but as an alternative along the lines of the drag coefficient for speed/distance estimates, you could include an efficiency coefficient option in the rider settings that defaults to 23.9% but allows us to alter it as with drag. Then the formula for the calories in the TCX file would be:

kC = (kJ/4.184)/Efficiency

I made this a new feature request. We can see if there are others interested in this. Generally we don’t want to add features that don’t seem to have a lot of people needing it. But maybe this will spawn other ideas as well. The speed adjustment was added because we had so many complaints about too fast or too slow.
