These are impossible to measure, but you'll notice them when you see them. They flat out write better code. Better code fails gracefully, is easy to read and especially nice to extend. Juniors seems to magically be able to ship features really quickly on that particular codebase and onboard really fast. If you dig deeper you'll see the 10x giving hints and feedback.
