To add to those numbers, there are an average of 108 stoppages per game (throws, frees, goal kicks, corners, subs, and kick offs)
So, if I was creating this 60 minute game regulation, I would probably have something like the clock continues for 10 seconds after the ball goes dead, then stops until play resumes. Given that 10 seconds is probably a reasonable time for a ball to get back into play after it goes out for a throw, for example. That'd cut the length probably by a few minutes per game so instead of a 10 minute swing you might be looking at 6-7 on average
