Quality of code is a rather nebulous term and there does not seem to be a great deal of agreement between the various definitions that have been given.

I take it what you are really interested in is something like probability of fault occurring per unit of use?

Isn't one of the purposes of things like SQALE to ensure that software having the desired characteristics is independent of experience? Yes, experience enters the equation but only as a cost issue, with more experienced potentially being cheaper in the long run.
