I do the same thing. Why go to the hassle of manually placing balls individually when the rack gets you there in 2 seconds? Robert

I think this conclusion from the article gives a clear picture of Roger Long's ability to evaluate aiming systems. Robert

I definitely practice less because of the scientific crap. It's the only way I can maintain a high level of play with minimal table time. In an ideal world, of course, I would practice a lot as well as do the scientific crap, but I'll take science over sucking any day :) Robert

I agree. This would be the ideal voluntary free market solution - like UL before the government meddling. The only technical problem I see is inconsistency within a given cuemaker's shafts. That may cause enough variation that simply testing representative models wouldn't be accurate enough...

No, only one: NR carom angle insensitivity. Using the word "about" seems to be clouding your judgment regarding the other 'advantages' because you're assuming the cut angle range that gives predictable NR carom angles holds for them as well. Unfortunately, they don't. Rolling distances, draw...

From the center spot to one diamond away from the middle diamond on the end rail is about 14 degrees. I guarantee you aren't getting 14 or more degrees of throw from sidespin alone while hitting the OB dead in the face. To hit that far over, I'm sure that you are actually cutting the OB due to...

I think another reason why billiard players may notice the table changing more than pool players is that we're primarily concerned with accurately banking cue balls instead of object balls. Since the CBs are accumulating chalk with each stroke and OBs and rails are only picking up chalk and such...

Thanks for posting the sample 'pushback' tables. I'm still unclear about your aim lines, though. Are you aiming the ball on a line at the corresponding point on the cushion nose (which means you contact the rail slightly before it), or aiming to contact the cushion at that point (which means...

Unfortunately, Marlow's analysis is much less useful than it could have been because he assumed in all of his calculations that the 'correct' rail height is 7/10 of a ball diameter instead of what every pool and billiard table on the planet actually uses. Hopefully, future analysts will stop to...

I understand your point, but it depends on how the eyes are used. Your argument is valid when pivoting (lol) at your neck or just moving your eyes in their sockets. However, you could also pivot at the CB as well by moving your head and always aligning through the CB center. I know someone who...

I'm pretty sure it's not adding up on paper for anybody. This seems to remain a mystery only to some (Patrick not included). Robert

Prelim results are posted in this thread. Finals start 10am EST today (Sunday). Robert

Thanks for the generous offer, Bob, but Doral Billiards and I are happy to provide the stream for everybody. This is my first time doing it, so I'm just happy to even get it sort-of working to begin with. :) Henry Ugartechea (USBA Southeast Director) will be helping with the streaming for the...

Thanks for spilling the beans, Bob ;) I was wondering about the difference since they had a few blue logo tables at the Seminole event this weekend. Does the new material prevent those annoying black marks on the balls that the leather ones sometimes made? They didn't seem to affect ball-ball...

That's probably the older American specification, but 37mm +-1mm is definitely the current height specified by the UMB in the doc I linked to. It's used for all international competition these days. 1-9/16" is 39.7mm, which is definitely above the acceptable range. These are excellent points...

From a table mechanic's perspective, why do you suppose pool cushions are proportionally so much higher relative to ball diameter than carom cushions? UMB carom regulations specify a 37mm nose height for 61.5mm balls, which gives 37/61.5=0.602 or 60.2% of the ball diameter. WPA pool...

Diamonds are not a good way to measure misses. Two diamonds sounds like a lot, but from the very shallow angle where it's possible to hit that high up the rail and still have the ball go in, two diamonds from the pocket is 2 degrees or less from the pocket center. Since every degree is roughly 1...

That agrees with the many scientific studies that show people's perceptions of enhanced performance from drugs don't always agree with reality when measured in proper observing conditions. Some drugs do measurably enhance various aspects of performance (albeit frequently with dangerous side...
