Wbat you need to understand is that the Superspeed and Artemis cushions are designed differently, therefore they're going to have a little different playing characteristics meaning they're not going to play exactly the same. The Artemis K55 cushions have a more rounded nose which means they're going to increase the friction contact of the balls, in such a way that the cue ball for example can spin off the cushions at a slightly greater angle than it does with the superspeed cushions. In the same respect, trying to shorten up a bank is going to have more effect on the artemis as well, yet transfer of spin to lengthen a bank will also provide better results on the artemis cushions too. But i feel that to truly understand the banking ability of any table, the player must first understand all the extenuating constance's that effect how a table banks. Loose rail bolts, thick or thin, or loose rail cloth, worn rail cloth, dirtly rail cloth, dead cushions, improperly installed cushions, cushions unglued. New bed cloth, worn bed cloth, type of cloth....the list goes on and on. What i see a lot of and hear a lot of, is players complaining about how a pool table don't bank according to the 3C banking diagrams! Well, i hate to be the one that gives out the bad news, but someone has to, most 3C tables don't bank according to the 3C banking diagrams drawn on a piece of paper either! Maybe in a perfect world, where the tables are kept in perfect condition at all times....MAYBE then they'll ALL play perfect, but down here on earth, you NEED to learn how to adjust you banks no matter what table you're playing on and stop fooling ones self into believing that you're a perfect bank pool player and when you miss a bank....its the tables fault!
