Any chance you remember where that measurement came from? I could use that with a client right now, given we're discussing a major refactor of about 25%-30% of the code base.
Have you been able to find the Thomas et al paper that supports this claim? I have been unable to find it, and others seem to have this problem as well:
I realized today I got it from somewhere else..
(Facts and fallacies of Software engineering)
Looking up the whole reference in that book gave me the title,
and googling that gave me the the paper
