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

kanzzo

hobby player
got an update on my table since got new rails 2 weeks ago:

9 foot Gold Crown V tournament edition (as before)
pocket mouth 107mm (PSF 1,1)
pocket throat 90mm (17mm difference so PAF 1.02)
pocket shelf 27mm (PLF 0.98)

so table plays now easier and better but TDF is higher (1.1)

here a video of my pool room with the required measurements for attacking my doctorate with honors diploma from Billiard University

here a video of my pool room with the required measurements for attacking my doctorate with honors diploma from Billiard University

noticed a difference to my last measurement
I measured the throat too deep last time (more than 2 inches back from the cushion noses)

correct measures are
pocket mouth 107mm (PSF 1,1)
pocket throat 97mm (10mm difference so PAF 0.99)
pocket shelf 24mm (PLF 0.98)

TDF 1.07

please delete my other two table entries, being measured incorrectly

Thank you for the correction. I'll update your latest listing and remove the others.

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 the TDF Excel spreadsheet calculator to get your results.

Got confused with this picture. Thought, my measurement should be, where second red line is.

confusing picture.JPG


This picture is clearer and this is the way I measured before.

orig.JPG


my pocket facing angle is 140° , so PSF 1.0

So the table measurements in inch (for better comparison)
9' Gold Crown V Tournament Edition (same model as the one from Marc Vidal)
pocket mouth size 4 1/4'' (107mm) (PSF 1.1)
pocket facing angle 140° (PAF 1.00)
mouth throat size 3 5/8'' (93mm)
mouth throat difference 5/8''
shelf depth 1'' (25mm) (PLF 0.98)

making for TDF 1.08

View attachment 587373

Here's the caption that labels that photo on the TDF resource page:

how to properly measure the pocket mouth and throat dimensions (at the intersections of the yellow lines, not at the labeled red dimensions)

This picture is clearer and this is the way I measured before.

Agreed. The illustration is much clearer.

Dave, please update my table measurements in this TDF forum with new slightly higher TDF (1.08) and better comparison (Inch)

I'm at 0.91 on my 9 ft Canada Billiards Black Crown 2, they have offer two pocket sizes , BCA and WPA, I went with the larger BCA, I suspect based on a rough estimate the WPA would place this table at 1.0

great list btw,

my .02, would love to see an estimate on a chinese pool table, having played on them it would top this list I'm guessing as they play harder than even most 10 foot pool tables, also the table they recently used during the world pool masters would be nice to see those numbers, and as beastly as those russian tables are, the comparison to pool is a bit off, if you've watched the game you'll know what I'm referring to with the short punchy shots at small distance, love seeing the measurement though

Post your measurements and numbers so I can add you to the list. Thanks.

Unfortunately, the TDF system does not work on tables with curved pocket facings.

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 the TDF Excel spreadsheet calculator to get your results.

I don't seen any 8' diamond red labels in the list. Here's mine (thicker pocket shims, but not double shimmed):

8' pro
4.5" pocket size
4" throat size
1.625" shelf size
TDF: 0.93 (mobile calc)

That's the TDF, but it plays like a SOB right now. Slates have dish, each on a different level, and every rail plays different. Ugh. For a commercial table I rescued out of a pub it sure needs a lot of maintenance.
