        There are 4 modes:
         MONITOR:
         - Use average framerate to determine framepoints.
         - If the framerate is below the minimum required framerate, exponentially drain the score
         until the framerate is stable or the drop zone has been reached.
         - If in the unstable zone, linearly recover the score.
         - If in the stable zone, increase the score by the recovery likelyhood (((30-framepoints)/30)**2) 
         but only if we're lower than HIGH power mode. Otherwise max out at the stable threshold.
         - If we reach the drop threshold, drop the power mode down a level and take note of the recovery likelyhood (((30-framepoints)/30)**2)
         and reset the score to the stable threshold.
         - If we reach the recovery threshold, enter fps recovery mode and go up a power level.
         RECOVERY:
         - Don't keep track of score.
         - Use the real-time fps to take a small average of the current frame.
         - Once the average buffer is filled, use the average fps to determine whether we stay in this power mode or drop back.
         - Framerate at least 58, 28 etc, stay in this mode and go back into monitor mode, and reset the score to the stable threshold.
         - Otherwise, update recovery likelyhood and drop back.
         SLEEPY:
         - If sleepy mode is enabled, the score is paused and we don't do any operations;
         Wait until sleepy mode is disabled.
         GRACE:
         - A grace period where the score is not changed for a certain amount of time to allow the average framerate to fill up.
         - Once the grace period ends, return to MONITOR mode.
