Has anyone really run a study of how code metrics correlate to
maintenance costs?  Something like "In this module, the complexity was
high, and we had to make more changes to it after delivery" for a
reasonable size system would be helpful.

Data like these would help to determine in what circumstances metrics
are useful.

By the way, how does one define "most critical?"
