On a lot of teams, code that a pair of devs wrote usually gets a lighter code review. Nobody wrote that rule down and nobody voted on it, but pairing earned it. Here's what the research actually says about that discount, why it's never one flat size, and what happens when dev + agent starts getting filed under the same category.

A one-line warning in my deploy log took my site down for thirty minutes. It didn't stop anything, the command exited zero, and it looked like every other line scrolling past. Software risk stays invisible until traffic hits it, and that invisibility is why the work that prevents incidents is the first thing a deadline cuts.

Nothing logs a 1:1. No ticket closes when it's over, and its best outcome is a prevented problem, which no system can count. Here's the 30 minutes a week I protect for each person, the short document that runs it, and what protecting it actually costs me.
