I finished my 30 runs and averaged around 6.27 wins. I can’t find myself on the leaderboard. I tried looking also around that average, but no success.
It’s updated in real time now and it starts from your first run and goes until you get at least 30 runs in and it keeps going after 30 runs for a total average for the entire rotation. All the runs count. You can’t just retire until you get a god deck and start your average from 30 runs starting form there. If you did do those early retires your average is probably much lower than you think.
