20 times a day in my case and 45 in case of another guy. If we suppose you code actively 6 hours a day it's like being interrupted 7.5 times a hour. That's "often" when compared to other errors.

To other kinds of compilation errors (I think this point was clear in the article)

If the compiler doesn't catch errors, most of them will go in production (you're usually not unit-testing all the possible type errors). I'm appealing to common sense here - It would be interesting to see if data confirm this.

This is a blog post, not a scientific paper. This is far from complete - it's just meant to be a good starting point. Factchecking everything is stated here would require an entire research team.
