Tom Dankowski's a good guy (my personal opinion), but he speaks for himself, not for the factory.
If someone wants a CZ tuned up the way Tom thinks they should be tuned, Tom's the guy who does that, not the factory. If someone wants a CZ tuned to factory spex, the factory does that.
I'm not interested in getting into a debate over which way is "better", or even what the differences are since the factory has no control over how Tom tunes machines up, nor does Tom have any control over how the factory does it. Both ways "work".
A few years ago before Fisher in California was put on the auction block, the original CZ tweak procedures produced by engineering dept. (that's me) were abandoned in favor of an easier procedure which however did not produce results comparable to the original procedure. (This is the "Old Fisher" I'm talking about which so many people mistakenly venerate.) After the manufacturing operation was moved to El Paso, we discovered that the procedures being used were not the original procedures I'd specified. We rewrote the procedures to conform to the original procedures insofar as practical, in light of stuff we knew now that wasn't known then, as well as accommodating a different manufacturing environment. Nowadays there's a lot less difference between a "Tom tweak" and a factory tweak than there used to be.

Figured I better post this, because the "Tom versus the factory" thing crops up occasionally on forums and gets overblown and misunderstood. Since Tom is not an employee of the factory I can't officially endorse him, but I can report what I read on the forums, which is that he has a good reputation. (And I've had enough contact with him to respect him personally.) If you want a Tom tweak, Tom's the guy to talk to, please don't bug the factory about it. If you want to have a CZ recalibrated by the factory, that gets done at the factory, but it doesn't have anything to do with Tom.
