That's right. A power meter and heart monitor are cool fitness gadgets, but completely unrelated to your goal. They would just put extra data into your recording. Like of you had a thermometer, that might give a little more contract and background to your rides, and it might give you badass points. But it won't have any effect on how many miles you rode. That's how it is with all the sensors available
except the speed one, which changes how your computer measures distance from GPS to wheel rotations.
