Continuing the derail, but oh well.
I guess I kind of get your point, but shouldn't anyone with any common sense be able to instantly know that 250k/10mil is way more than 0.025%? That's more than an editing mistake, it's an error that should be evident as soon as it's said. Unless you're ******ed when it comes to numbers I guess. It's off by two orders of magnitude!
Also I'm not a sewer engineer, or an engineer of any sort anymore. But your point seemed to be that only nerds care about mathematical accuracy? That's pretty sad.
