First, I count just over 400 kpsi which I read is the low end of what is customarily called a 60 raj rug. Certainly 55 would be more accurate, but I don't see that designature much.
Secondly I read that almost, if not all, Tabriz rug over 50 raj have a silk foundation.

So where have I errored. It's a beautiful rug I know that, but am I counting too high, I really don't think it is silk, so is what I'm ready internet over generalization.

Size is 52"X87"

Thanks for any clarification.

You're right in that picture which I hadn't counted before. The attached picture is the one I was getting 20 on. Maybe 20 is a streach, ut awful close if I can focus my eyes.

Both the pictures where taken in the same area, you'll notice the same green leaf in both.

But what I read is anything over 50 raj and I was counting this rug is over 50, but correct me if I'm wrong.
