He casts wyrmwaves for every action that you put on an enemy. So ideally during one summon of bahamut, you want him to do 11 wyrmwaves (and 2 ahk morns), though this isn't always possible and you'll get better at it. This is why you want to wait to summon bahamut until you have your aetherflow back from your last dreadwyrm trance.
