You have to know "RPM Math."
God this stuff and these screw-ups are so annoying. And they really shouldn't be difficult.
Please get this U.S. regulation thing going so hopefully we'll have sites that can get this stuff correct. RPM and Merge just hurts themselves with every issue they have like this. I generally like Seth and I wish I could be more patient with this stuff. But it just bothers me to see issues like these.
