Mac OS 9.2.2.2?

Well, my father keeps a collection of all his old computer magazine cover CDs (or most of them anyway) and when browsing through his collection I found a rather peculiar CD that listed one of the patches included on the CD as "Mac OS 9.2.2.2" As I don't have a Mac running OS9 anymore to test this (My G3s run Tiger, although I could stick 9 on one) I have no way to check if this is in fact some unknown update, or if (this is the more plausible explanation) the CD has a typo on the front and that it is in fact just plain old 9.2.2. Has anyone ever heard of this patch with an extra .2 at the end (Yes three .2s) and if so, is it better than the regular 9.2.2? (And if not should I go ahead and reinstall 9 on one of my machines to test this?) Also if it does turn out to be some rare update (and admins don't object) should I try uploading it to the Applefritter file archive?
