BBB probably has a more expensive and specialized method to test bbs.
Ok that's probably fine, I was thinking it was some ghetto setup and drawing wild conclusions from that.
And you never know, to make things commercially viable sometimes you do have to use "poor mans" setups like that if it's deemed "good enough" for the application. It's not like they test every BB, they probably take a couple samples from each batch and extrapolate based on that (kind of like how stringent SNELL testing is with needing to test every batch).
