We didn't really get into those topics in the two-day school. I don't think we were really going fast enough to induce significant lift-off oversteer, though I did feel it a few times. Initiating oversteer with the brake is what we were supposed to focus on the most. Someone asked about handbrake turns, but Dave (the school owner) said you so rarely actually need to use it in competition that it's not something they include in the curriculum.
"Smoothness" was not a priority - if anything, most were asked to be more aggressive.
