If you ride all-out for one our the AWC component gets spread out over the full hour and added to CP. If you sprint all-out for 30 Seconds the total power available is roughly CP + AWC/30.
But in the context of this discussion, it's worth noting that AWC, FRC, W' or whatever you might call it can be rebuild during a ride during periods of sub threshold riding. Total anaerobic work for a ride can be much greater than AWC.
