> discovery does not bring about its existence.

I would argue that it does but this is a matter for phenomenologists. The practical result is that it's as if the bug never existed. Beyond that let's agree to disagree.

#93 No hard data. How would you even begin to measure such a thing? No two software shops are the same, hell no two projects within the same team are anywhere similar. How to baseline? What about the impossibility of a control group for a software team?

I find it interesting that a power log distribution would result in the kind of behavior I am describing: relatively small impact for even fairly large variations in the number of tests applied to a project.
