Interesting, SiphonX. Thank you for the analysis.
Apart from those, games rarely took longer than one hour. The average game length was 45 minutes, even including the 3h game.
While it is a comparative relief to see that the longest game only(?) took 3 hours, the average length is in reality no consolation.
It would be interesting to know if the losing teams in an average game of 45 minutes simply called a halt, or whether they were in truth, really annihilated. I suspect the former may be the reality.
