W prime meter in the GUI.

Just thinking out loud, any time spent above my CP (Watts x Time =Joules) that could be subtracted from my W-prime (KJ or Joules), and be shown like a battery percentage of how much W-prime I have left.

This would be great for learning how to manage your efforts. I image this would be similar to a Normalized Power when using FTP. BUt I would find a "battery percentage" of W-prime more accurate of what I could do in a race and easier to understand.
