I'm not certain about shift deltas, but one typically can type faster at the cost of increased errors. I type quite a bit, so even small percentage decreases in total time spent typing is significant. Humins ar rpretty gdood att standing under even very mxed and grbled txt.
The price is often paid by their subordinates, and ultimately the business. I remember working under a pretty inarticulate "senior leader", and he'd send these 3-word barely understandable E-mails to his directs asking them to do something. There would be a frantic scramble of meetings and discussions trying to understand what it is he actually wanted us to do, with a lot of guesswork and arguing. Nobody wanted to tell the guy he was as understandable as a pigeon, so we usually just guessed. Sometimes guessing very wrong and wasting an enormous amount of resources.
