That would be nice, but the TDF system, in its current form, only applies to pool tables with flat pocket facings. Curved pocket facings would require a totally different analysis and different measurements.

Currently, the TDF system only takes table size and pocket geometry into consideration. There are many more factors that could be taken into consideration (cloth type and condition, ball conditions, pocket facing and shim properties, rail and cushion conditions, table levelness, humidity, etc.), but we decided to keep the TDF system as simple as possible, while still capturing the most important elements of table difficulty with as few measurements as possible (with the measurements being easy and free from qualitative judgement). For more info, see the table difficulty (TDF) resource page.

Do these Table Difficulty Factors apply to a Snooker Table. I'm getting a NEW-TO-ME Brunswick 6-leg Arcade... 10 foot Snooker with #7 irons.

The TDF (in its current form) applies only to tables with flat-facing pockets, so it doesn't work for snooker or Chinese 8-ball tables.

Sorry,

Nobody has posted info for a new or modified table in a while. Please post measurements for the tables of most interest to you (and others).

Thanks,
Dave

_______________________________________

Based on ideas from previous threads on this topic (tight pockets thread and pocket answers thread), and based discussion in the Billiard University (BU) thread concerning how to account for table difficulty in scoring and rating drills like the BU Exams, I decided to create a system for determining how difficult a table plays (based on table and pocket geometry only). It is described in detail in the Table Difficulty Factor (TDF) document, which is convenient if you want a printed copy.

Here's how it works:

The Table Difficulty Factor (TDF) is a percentage measure of how difficult or easy a particular table plays. It is based on table size and the three corner-pocket measurements illustrated below. If the cushion is not 2” (5.1cm) thick, measure the throat size 2” (5.1 cm) back from the cushion noses. You can lay down Post-It Notes or masking tape to better define the lines and intersection points to help with the mouth and throat measurements. If you have an angle-measurement device, you can measure the facing angle directly instead of measuring the throat size. The pocket shelf depth should be measured from the pocket mouth line to the slate top lip edge (where the pocket opening first starts).


Four factors are used to account for table size, pocket size, pocket facing angle, and pocket shelf depth. Each factor is a number less than, equal to, or greater than 1, where 1 indicates average or standard. By multiplying the four factors, you get the TDF which is a good measure of table “toughness.” If TDF=1, the table has an average level of difficulty; if TDF>1, the table plays more difficult than average; and if TDF<1, the table plays easier than average.

The four factors are defined as follows:







The total Table Difficulty Factor (TDF) is then calculated by multiplying the four factors:

TDF = TSF x PSF x PAF x PLF

The TDF can be used to adjust numbers from any scoring or rating system like the Billiard University Exams, “playing the ghost” drills, the Hopkins Q Skills drill, or the Fargo rating drill. An effective score, taking table difficulty into consideration, can be calculated with:

(effective score) = (raw score) x TDF


NOTE – The TDF and effective-score numbers should not be interpreted too literally since there are so many other factors that contribute to how difficult a table actually plays (cloth type and condition, ball conditions, pocket facing and shim properties, rail and cushion conditions, table levelness, humidity, etc.). Here’s a rough scale one can use to put the TDF factor in better perspective:

I'll add this to my "list," but it won't be easy. I need to do do a geometric analysis similar to TP A.5 and TP A.6 for rounded pockets, and I need to do some testing on a Chinese 8-ball table (to which I don't have access).

But excellent idea!

Regards,
Dave
