This year, I played in leagues with 2-hour limits and 90-minute limits. It was unusual for one of my matches to time out. In the 2-hour league, I played 32 doubles matches and one singles match. Only one match was not completed (6-7, 7-6), and the opponents began stalling the minute they won the first set. (The stalling was quite brazen: Drinking and chatting on Coman tiebreak changeovers, having conferences after every point when server was ready, etc.) All of the other matches were completed. In the 90-minute leagues, I played six doubles matches. All matches were finished. For me, timed matches haven't been much of a factor in how my matches have turned out or how enjoyable they have been.
