Re: Your perspective on the experimental format
I attended 5-2 match yesterday that took 3 hours 2o min to the point where the 4th point was decided.
However, that included a good 15 minute delay waiting for # 4 doubles to finish since a girl in that match was part of the six in singles.
So official match time if you stopped doubles at the point and then stopped singles at the 4th match point would have been 3 hours 5 minutes. And it was a decent match with some question of outcome for a bit.
