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

T411 said:
I think your you should title it TPF… Table Preference Factor. The most difficult table is a table that has not been leveled well and nobody prefers that. Even then your competition plays on the same table. Everything else is preferences and that personal.

There are many factors that can affect how a table plays. See the "Doesn’t side pocket geometry and other factors like cloth and cushion conditions also affect a table’s toughness?" section on the TDF resource page. I think the TDF name is still appropriate based on all the other info on that page.
 
Here's the latest summary of all data reported to date:


​
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.

Its because Dr Dave assigned 3x the factor for pockets than table size.

He has a multiplication factor for each of:

Pocket width
Pocket depth
Pocket angle
Table size

So if a pocket is a hair "tough" in width, depth, and angle, it would be .9 x .9 x .9 =0.729
The pocket thus accounts for 3 times as much as the table size in his calculator.

This does not match real life. Table size is far and away the largest factor in if you make the ball and get position to run out.

The math does not work out that way. The fact that pockets have more variables (3) does NOT mean that they are getting 3 times the WEIGHT. There is no universal unit for comparing table length with pocket angle. So each is given a weight to reflect the degree to which they affect table difficulty. You might complain about those weights, but the math is sound.

Thank you kindly
