whenever i hear or read a google SRE resource, i’m most impressed by their back of the napkin calculations. it’s a skill i wish i had but don’t have opportunities to do it or even validate that i’m in the right ball park
Is it a skill or do they just have better access to data to base their calculations on?
Mostly a skill, it is not really taught in CS because implementation is cheap but physicists, traditional engineering (electrical etc.) and some business schools all use aspects of estimation.
