No, the base levels were during the development cycle.  So the first internal checkpoint would have bee 10.1A, beta might have been 10.1G or something like that, and production release a few baselevels later so L.  The release would get whatever base level designation applied to the final baselevel of the release cycle.

There was also a DEC convention, I don't remember if RSTS used it but I know RT11 did it at least at one time, which is to use the V prefix for production releases, X for internal development baselevels, and Y for beta.  I have tucked away a copy of RT11 Y02-20, so a beta snapshot of the V2 release.
