Help with how building attack is affected by garrisoned units?

I'm pretty sure that a tower filled with hand cannoneers or janissaries does much more damage than if it has archers in it. I'm pretty sure that the variables that affect the building's attack/# of missiles are number of units and the attack of those units. Teuton towers hold twice as many units and you can make their bombard tower fire 2 cannonballs with much more AP by filling them with cannoneers.
