It's a bad saying either way. It's too context-sensitive and riddled with semantics to draw anything of use from. Sibling comments already showcase this. Not only that, it doesn't take into account you don't jump from 0 to 100 in a single go. It's more of a curve where you'll be decently productive early in the journey, and spend most of your time getting the remaining 20-10 figured out. And with most companies generating pretty decent profits, I'd wager being halfway your full productivity is already close to a net profit for most established companies, which negates the entire "the company runs at a loss for several months!" spiel. That's not to mention that saying makes it very easy for companies to deflect responsibilities onto ICs, as if expecting everyone to know everything is "just how it should be".
