The reason for this is that you likely have unrepaired Red Labels with the rails slightly tilted down from the "proper" down angle.. This causes the rail edge to "lift up" the balls as they hit the rail and bounce off. This effect is magnified when humidity levels rise. This also has the affect of shortening the response angle if you brush a rail while shooting a ball into a corner, often shortening a shot that would have "slid in" off the rail, into an angle that hits the pocket facing. I bet those tables ping pong the balls back and forth offtherails, to the extent it almost seems like balls "pick up speed" when struck into a rail firmly...
You can test if this is the issue by banking the cue ball at the middle point of the rail from the center pocket, and seeing if it banks into the corner... I had a Red Label in Florida that banked a FULL diamond short of the corner, when hit with a moderate center ball hit. It is possible to repair the downangle, but it takes some time, and is not exactly cheap. Requires the subrail to be rebuilt/recut.
My Red Label quite likely cost me a win in the One Pocket division at DCC against John Morra, the year he won the the Banks. I had him down 2-1, and had multiple shots at a cross corner to finish him off. My table required not only overcutting all cross corner banks, but also precise speed control. You could only get anywhere close to a "normal" angle on banks, if you rolled them. Sure, if I was better at adjusting to weird table conditions, I might have been able to compensate, but I am a weekend warrior, with not a ton of time to practice. That year I was between jobs for a few months, and ended up wiring in some bad ways of hitting banks, that did not move well to the Blue Labels Derby was using by that time.
