Crazy stuff can happen, too.
A few weeks ago, I shot a seemingly simple 2-1 kick on a GC4 I play on regularly in a DC suburb. The shot was way off.
After my match was over, I practiced the same 2-1 bank and it was quite short. A very slight amount of running spin solved the issue.
Then I practiced the classic Corner 5 shot. I could not get the CB to go into the opposite pocket from where I shot hitting the third, second or first diamond. Didn’t matter the speed or spin.
Just a week earlier, the same table kicked just fine and I pocketed the Corner 5 shot consistently hitting the second diamond.
I’ve never played on a table that was so off from one week to the next!
