Did you watch the video I posted? Did you notice the way the balls opened? There are other factors as well. The balls Mosconi would have been playing with would not likely open with the slightest touch. Most racks would require some work to get through.
The pockets also react differently as do the rails. Balls hang up due to the rail friction. On Jaysons table the balls react like they are polished with silicone. They flew into the pockets and break shots balls went everywhere.
Again, in the video I posted, that looks like what a normal table and balls play like. I feel on Jaysons table they did everything they could to make runs happen. That is all I am saying.
The table Mike and Earl were playing no one could run that kind of number. We were not there, but I suspect the table and conditions Mosconi did his run on also makes it extordinaty. No one was polishing the balls every few racks. Also the more confining nature of the smaller table.
Let's face it, what Mosconi did was amazing. Most all players then and up till now had life time high runs at best in the 300s. If all tables played like Jaysons, forget about it.
For me this is not a debate, it is my opinion from 60 years of playing and watching pool. It's how I feel.
I would like to see John's run to compare the two.
