Table Difficulty Factor (TDF) for measuring table "toughness"

I think it's a mistake for pool rooms to have tight pocket tables for the general public. If pro level players prefer tough tables, a poolroom can always set aside a handful of tables for their action. If an intermediate player wants to work on cleaning up his/her pocketing technique on a tougher table a few should be available. But the average player struggles to make shots on an easy table. A tough table will make the game so much more difficult for them, they are not going to get any pleasure out of playing and will quit. It makes no sense. Do people like pool torture?

Sorry, but the TDF system applies only to flat-facing-pocket pool tables. A totally different system would need to be developed for tables with curved pocket openings.

Here's the latest:


​
Calculate your Table Difficulty Factor (TDF) to determine how tough it plays relative to other tables. Only three pocket measurements are required, and you can use the TDF calculator or TDF spreadsheet to get your results.
