Thanks for your replies; I greatly appreciate the benefit of your knowledge, experience and insights. The link to the ball roll-off tests isn't currently active, but may be restored today. The table installation was completed on 2/16/18, and the ball roll-off tests were done on 2/27/18. No levels have been used since installation, but a fitter will be back next week with a full box of equipment. The manufacturer plans to replace the Simonis 760 cloth we preferred for the Golf game we normally play, with Strachan 6811 cloth, normally used on snooker tables, to solve the ball roll-off we've observed--they've viewed the videos we made. Of course, re-leveling the table will be part of the process.
