It sounds like he is using a kestrel 5700.
If that's the case they have applied ballistics custom drag curves.
They aren't wrong end of story.
To me, the culprit is the 1.3 high at 100 for a 200 yero
Actually zero at 100 and try your data out from that.
I have seen most things in my time.
Just had one the other day with the guy having problems.
Have you zeroed?
Yep, shows me a tiny 3 shot group through the dot.
I went and validated and it was coming up at a lower speed than I though it should be.
Rang me to say way low at 350.
Fucked if I know,recheck the zero.
Guess what, zero out, fixed that and bang on out to a km and back
