You’re inserting things into the question that weren’t there and tearing it down. Nothing was said about a “routine performance” which is certainly common enough today to that it is worth asking but is not always the case and not always common through time.

Regardless, it is never a bad thing to be overly cautious and redundant. I once heard it said that if necessity is the mother of invention, redundancy is the mother of victory. That is how I view the question.

They’re exploring an ambiguity in the question. No need to tear them down.

I feel similarly. If I’m getting a common heart surgery, I’d like to go with someone who does it every day. Reading a textbook is a negative signal that they do this frequently. (A checklist, on the other hand, is not and I’d be happy to see it used).

If I’m getting some rare surgery or there’s a complication, then seeing the doctor read a textbook makes sense. They can be very experienced overall, but not in this exact case.
