And if you have to bounce around across different codebases, you obviously go a lot slower.

If I'm pounding out the same boilerplate code I've written for every greenfield app, I can go at a phenomenal speed. But if I'm put into code I'm not very familiar with, 98% of my effort is understanding the existing code and 2% of it is making that 1-10 LOC change.
