Good question. For me, in my line of work, it allows me to very quickly and on the spot (similar to John's blog post) confirm or deny if something passes the sniff test. If someone says "but that will cost X!", it is a superpower to easily refute or corroborate that. Along those lines, if someone throws out that doing Y will easily provide Z amount of value, simply being able to work through the assumptions the person made when coming up with Z, and offering up your own Z' if necessary, is very advantageous in a live, synchronous setting like a meeting with a client.
