xPower is an alternative to normalized power.

It's using a 25 sec Exponentially Weighted Moving Average instead of 30 second moving average to Address Variability:

A 30 second moving average (30s MA) does not account for the fact
that physiologic response to stress decays with an exponential rather than linear time
course. A logical / intuitive solution would be to address this with an algorithm that
provided an appropriate decay pattern. Theoretically, an exponentially weighted moving
average should provide a more realistic model. (This was in fact the initial basis for the
development of the xPower and BikeScore algorithms.) We selected a 25 second
exponentially weighted moving average (25s EWMA) based upon the fact that this should
track consistently with oxygen kinetics.
