3:1 actually, as there seems to be this phobia about diving in a three, which having been trained by GUE, it is actually the best way to dive. Its very common on a boat to hear people saying threes are bad, which is strange to me.
So I'd say three students, that way two perform the drill, one can watch and learn, and then take turns. They get used to diving as a team, and also the instructor can earn some money as they need realistic numbers to do it for a reasonable price.
