I can't stress enough how IMPORTANT measuring everything on your own is. That is if you understand how to measure... I work in optics manufacturing, metrology is no big deal to me. It might not be as easy for some, I'm not picking on anyone, I'm just stating the facts.
Measure it, calculate it, and you will probably see the same numbers spit out

Measuring it yourself is really important if you want things to be spot on, it is safe to say ERD's can have a tendency to vary even with the same rim purchased at the same time.
