L5 or above there's normally a lot more communication and planning, which pulls down the mean significantly. In migrations you typically need to subtract some old code in the end, and it's not uncommon to result in net negative LOC (if the migration is ever complete). For L4 maybe there are more days where one can do several hundred LOC in an afternoon than L5, but there are also many days that result in 100 or less over an entire week, because there's testing, debugging, profiling and figuring out what to code. But, maybe I'd be wrong about Google. Afterall, it might be easier to dump lots of code into the codebase if there are 10 independent chat apps in development at any one time.
