ordinary Brunswick Metro:
TSF (9 ft) = 1.0 PSF (12.5 mm) = 0.95 PAF (20 mm) = 1.04 PLF (45 mm) = 1.03
TDF = 1.0176
And now, the king of them all :grin: with a TDF of ... 1.722 :shocked2:
Yeah, it's a 12ft Russian pyramid table. We used to play snooker with pool balls on it until a real snooker table was set up nearby. Forget about playing down the rail, and one needs to be as precise as a surgeon to make a ball that is closer to the cushion than the middle of the table.
TSF (12 ft) = 1.25 PSF (72 mm) = 1.45 PAF (125 degr) = 0.97 (I disagree 125 makes this table easier than had it been 144, LOL) PLF (25 mm) = 0.98
Thank you for posting these, especially the "sick" Russian Pyramid table. That one is so far off the pool-table charts, I wouldn't put too much weight on the TDF numbers.
This is what I got for your two tables, using the latest TDF document (... it looks like you might be using an old version):
Vahmurka -- 12':1.25 -- 7.2cm:1.55 -- 125deg:0.97 -- 25mm:0.98 --

Vahmurka -- 9':1.0 -- 12.5cm:0.91 -- 20mm:1.04 -- 45mm:1.03 --
0.97 (Brunswick Metro)
