1st - 24h (opening season)
2nd - 24h (spring season, RL didn't invent blitz yet)
3rd - 10m (blitz season)
4th - 24h (donkey season)
5th - 20m (blitz #2)
6th - 12h (summer season, current one)
7th - ??? (the next season)
I'm wondering what is the probability RL will do blitz again, effectively slicing blitz seasons between longer ones?
