Math check

[DRNewcomb]

I'm installing a scope using Burris Signature Zee rings with the 0.01" eccentric inserts. I just want to double check my math. The ring centers are 4.8" appart. Using one eccentric ring set should give me:
arcsin(0.01/4.8 )*60 or 7.16 MOA of elevation. Using two in opposite orientations should double that to about 14.3 MOA. Right?

Arcsin and arctan are the same to several decimal points at low angles.

Thanks for reminding me just how much I forgot. Tom

7.16-MOA @100yds from 0.010" insert is what I computed also....
