I know that at Inland Empire, we were calling fouls during practice matches. And if we called a foul at that time, we generally went over to the team and said "hey, we called a foul on you, here's what it is". By quals, most teams had figured out what sort of actions would cause a foul/card. (Though one of the first fouls called in quals was a yellow card--that was also the last team to touch their controls during auto!)
