Yes, it helps a lot, especially for those moments when an action HAS to be finished, PRONTO, and returned for an event. I concur with the "fastest rise without the bounce". Springs seem stronger as centers loosen with wear, but they aren't. In Linfield College's performance instruments, I've found a lot of what seem to me overly loose centers, even though there is no side motion. Controllability suffers, and to avoid the bounce coming out of check, springs would have to be too weak for the quickness of jack return which I would like. I'm gradually trying to break loose some time to repin all hammers and many wippens and rep levers on these instruments, with great improvement in feel. Luckily we don't have the seasonal high humidity to contend with, just lots of use. Given the amount of use these pianos get, pinning to six swings seems not all that economical, since they'll just get too loose again too soon. I like closer to 4, so long as pianos don't have a weight problem, and friction elsewhere (such as keypins) has been minimized. Of course, 4 would be ill-advised in winter in places with damp summers.
