I'm conflicted in this. Ok the one hand, a lot of things here ring true, and AIC (Ass In Chair time) is a relevant indicator for work except... When it's not. Quality is definitely a thing, and it's hard to measure. Sometimes you work for a couple hours on something, and your revisit it later and realize the quality just isn't there and you have to do it over. Then how much did those hours you put in really count.
