June 4th is Sunday, so it'll be sometime between 5 - 8 PM, right? If "up to 15 drivers on track," we should all be able to be on the track at the same time?

Is "5 minutes of qualifying" not the same as 5 minutes of practice?

Either Super Race or Super Grand Prix, does everyone get to spend all 20 min. or 35 min. on the track?

I have not done this go-kart racing before, but I'm assuming that even 20 min. of track time still goes by really fast?
