I will start of by saying thanks to those willing to help out.
OK, I did find a discrepancy in my data.
sight height was off. 1.5 vs 2.054 actual.
I made changes to the calcs but didn't correct everything.
Below is my chart.

It is still not what my actual data revealed. But better. If someone see's a discrepancy, I'd appreciate it.
I'll double check chrono and zero to see if changes. I haven't checked tracking on this scope. I would hope I can trust a NF.
Regarding hard info.
