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

I dont think this system is 100% accurate

Ok, here is my personal experience with TDF and two tables I have shot a lot on:

I have access to two tables:

1) An oversized 8 foot table with 4.25" corner pockets and 4.75" side pockets and TDF=1.03
2) A 10 foot table with all pockets 5" except one corner which is 4.5" and TDF=1.02 (with all corner pockets rated at 5")

On the 8 foot table very often I can throw out 7 balls and fairly consistently run them out with ball in hand. Sometimes, if I'm playing good, I can do so with 8 balls. Playing 6 ball on an average day I win about 75% of the time in a race to 7.

On the 10 foot table its another story. I've never really been able to consistently run out 7 balls with ball in hand for an extended period of time. I even have trouble beating the ghost at 6-ball at all.

I recently spent about 5 days straight playing on the 10 footer and I did see gradual improvement (I don't play on it very often and when I do its normally just for 2 days over a weekend).

Basically, from what I can see, the difficulty of table size has much more to do than just pocketing. Yes, overall the 10 footer's pockets are easier as they take balls not hit cleanly down the rails easier (except on the 4.5" pocket...) and allow more cheating of the pocket but when hitting the same shots on both tables on the 10 footer the shots need to be hit MUCH harder for shape which makes cueing accurately much harder. Also, speed and direction control are much harder on the 10 footer when one considers the shots are hit harder and that direction errors increase as the distance the cue ball travels increases.

This isn't even taking into account the biggest problem which is reach. I am only 5'8" which means that on the oversized 8 foot table I can reach 99% of the shots without stretching. On the 10 footer at least 10% of the shots I'm putting a good stretch into the shot which often causes a miss. The more I play on the 10 footer the better I seem to be getting at avoiding these reach shots, but the solution is often to take an even longer shot which doesn't make things much easier.

A solution to this reach problem problem seems to be to play center table shape much more often than I would on the 8 footer.

So, from the TDF scores, the tables should play almost exactly the same difficulty, but they don't. The 10 footer is MUCH more difficult (at least for me).

Please post the detailed TDF info for both of these tables, and I'll add them to the list.

Thank you for sharing that. The TDF systems is definitely not perfect, and there are many other factors that contribute to how difficult a table actually plays (side pocket geometry, cloth type and condition, ball conditions, pocket facing and shim properties, rail and cushion conditions, table levelness, humidity, etc.); and as you point out, actual difficulty level will vary some from one person to the next. However, the TDF system provides a good average measure of table toughness with only a few measurements. For more info on how everything was decided, see:

Thanks again,

Just curious as to why one of your 4 corner pockets on the 10-footer is 4.5 inches whereas the other 3 corners are 5 inches? For some reason could that be for practice purposes, or some kind of error made by the last installer who set up that table? Just seems very strange.

Modified Ruxton Billiard, 7' one piece slate .85, 3 7/8" 1.25, 7/16" .99, 3/4" .98, I got 103. Without the shallow shelf, it would be too tough for me:cool: Dr. Dave, I got this table to run your drills. Thanks for all you do:thumbup:

FYI, I've added your table to the list.

Dr. Dave, I got this table to run your drills.
So should we expect some entries from you in the BU Exam Challenge?

Thanks for all you do:thumbup:
You're welcome. I aim to swerve. :grin-square:

Thank you for posting,

Here's the latest:

Calculate your Table Difficulty Factor (TDF) to determine how tough it plays in comparison to other tables. Only three pocket measurements are required, and you can use the mobile-friendly online tool (created by "Isaac") or an Excel spreadsheet to do the calculations.

To Dr Dave. I've noticed alot of people getting the less than and greater then values wrong when it falls exactly on the cut off point. For example for a Diamond pro am pocket of 4 1/2 inches i've seen values of 1 and 0.95. Would it not be better to get rid of the less than and greater than and just say if it falls in the cut off point then do a average of both values. In the example I listed above it would now be 0.975. You could use this approach for all values that fall right in the middle and it would be less of a cliff face between sizes. Just a thought that I think would make it better :)

Why would a ProCut Diamond be less than 1.00TDF?? 7ft or 9ft? We measured one(9ft ProAm) at the' hall and got 1.03 iirc. League-cut Diamonds usually are in the .96-.97 range.

To Dr Dave. I've noticed alot of people getting the less than and greater then values wrong when it falls exactly on the cut off point. For example for a Diamond pro am pocket of 4 1/2 inches i've seen values of 1 and 0.95. Would it not be better to get rid of the less than and greater than and just say if it falls in the cut off point then do a average of both values. In the example I listed above it would now be 0.975. You could use this approach for all values that fall right in the middle and it would be less of a cliff face between sizes. Just a thought that I think would make it better :)
Thank you for the suggestion, but if people use the mobile-friendly online tool or the Excel spreadsheet, there is no problem. I think a bigger problem is not making the measurements carefully and properly (according to the instructions and illustration) within an accuracy of 1/8".

Regards,
Dave

Here's the latest:

Calculate your Table Difficulty Factor (TDF) to determine how tough it plays in comparison to other tables. Only three pocket measurements are required, and you can use the online mobile-friendly TDF calculator (created by "Isaac") or an TDF Excel spreadsheet calculator to get the results.

Thanks, once things open in my area I’ll take more measurements of tables.

Table plays fairly close as it did before with the exception of pocket speed. You really have to be aware of how hard you’re hitting the cue ball.

I didn’t get all the measurements for this table, but it’s a tough one. Sub 3 7/8”. Thought I’d share.
