I guess this won't be pulled?  The reason it no longer has lines of code is that it is a median, rather than a weighted average.  No reason to weight it if it is a median.  We have the problem that the code coverage shows our user model having a huge number of accesses, since most functional tests use the user model, and so the average is skewed a lot - and even though most of our code is only covered a couple of times, the average is over 600.  It seems pretty meaningless in our case.  Perhaps others do not have this problem.
