Hi it seems the pet armor is not calculating correctly on the spread sheet.
This may only effect tenacity pets I didn't do to much testing trying out other pet branches
Basically with all the armor talents and the tree bonus of 10% your pets armor should increase by at least 150%
I might be wrong about the tree bonus though im not sure. So for safety i tried just 140 percent. My pet 6724 my bonus armor 3116 * 1.40 = 13.7k
The sheet calculated as 12.5k
I wrote a much larger post with more attempts to calculate but the page timed out and I lost it
I hope this helps... I know this is such a minor thing
I didn't know the right formula or the password to the sheet so I didn't try and fix it.
