Ya, i guess that's the only way, so it is important to tune in to the match live. But my gf was irritated when i keep looking at the match progress while we were having dinner. I think this game might cause break ups
At 5-10 minutes per game, I doubt that 20 minutes max of the day will give you issues. If your gf gets irritated that you don't focus fully on her for 20 mins, then I think you have issues that are more relevant than T11..
