If 100 is the typical productivity of a smart person when she's making the technical calls, picking the tools, and writing a new system, most corporate environments expect software engineers to function at 5-10-- maybe 20-30 when they get to senior dev roles. The problem is that if you're used to 100+, that feels like being at 0. It's demoralizing when your productivity is a rounding error for environmental reasons that aren't your fault.
