Ah, statistics.  Ah metrics.

Given most outliers are now in the bug database can you perhaphs break 
it down by area and, hopefully, more usefuly, look at each area's change 
rate.

It is the change/progress that is important, not the absolute numbers. 
A lack of change that is of concern.  For instance, I worry about build 
and remote problems.  The former definitly makes progress, the latter 
less so :-(

PS: And metrics are made to be abused.  As soon as people know the 
metric that they are being measured by, the quickly addapt their 
behavour to make that specific metric look better.
