I think it's not a bad metric if you have hired someone fitting right into your current stack.

Now I am sure you had cases where you hired someone that didn't quite fit, but seemed interesting, and you were confident they'd get up to speed and pull their weight in a reasonable time frame (3 weeks ~ a month ?).

I'd argue focusing on the second category of hires as a target, and consider it a lucky event when someone exactly matches what you're doing, can lead to a more stable/less homogeneous team.

That's a fair point. In the life of my startup so far, we haven't been blessed with the room to allow us to hire people that we don't think will be productive for a month. For an established company though, I agree it's a totally reasonable measuring stick for good hires.
