Based on my experience and observation, 85% of cops range from competent to excellent. Even heroic. That number is too low, not acceptable.
Imagine a large dental practice of 100 dentists.
85 of the dentists range from competent to excellent. But 15 of the dentists deliberately hurt their patients, and make problems worse. Would you respect this practice? Would you go there?
Given my experience with dental work I think you’re being far too generous about the number of good ones, haha.
