I know the site, but thanks. It's a good one.

The mir-1 lens has a resolution power of 45/23 l/mm (pairs or singles?). It seems to be a low number atthe corner and so.so at the center. But I don't know if that numbers were taken at wide open (I don't think so) nor the contrast used.

Russian lenses used different measure. It can't be compared to western MTF. Probably sharpest russian 135mm lens - APO Telezenitar 2.8/135 is measured 53/40 l/mm.
So, MIR-1 is very sharp in center, but corners lacks.
