I don't have to worry about this because I'm not running an alt, but the AH used for starting should be accounted for because your alt has to replace that energy into the battery using fuel. Anyone have starter amps/warm engine info?

One of the benefits from running at 18V is the almost instant start when the engine is warm.

Added: I see this is taken into account in his wikki. I think the higher idle speed after restart is probably because of the load of the alternator recharging the battery.
