It's about matching the impedance. All a MPPT controller does is vary its effective input impedance to try to get the most power out. The correct algorithm depends on the characteristics of the source.

For my senior design project, I actually tried implementing MPPT for a stationary bicycle generator. I managed to get it to where it worked pretty well when I used it, but goes unstable when my classmates tried to use it. Probably because the MPPT algorithm was expecting the peak in the "low RPM, high torque" region when (for example) Sarah is more like "high RPM, low torque"...
