I am always chosing the stars for this business in
convenient position.
Locating two good pairs at the SAME distance is
of course very hard.

But I have large statistics, with stars and lunars.
It is only a small part that I presented.

I also don't think that the scope is relevant.
What sort of deficiency in a scope can lead to
a systematic bias? I suppose, only collimation.
Collimation I checked, and in general, it can give only very small
error.
