Lenses for film in LF and MF

I found this lens test for large format:

Here is medium format:

Really a large work in testing but I am sceptical about the result. Not that is it wrong in itself but if you run a photo test in scale 1: 20 the focus must be perfect and film plane and test chart must be perfectly parallel. Look at the Perkeo fold camera! And look at the edge results for many LF- not very good. Compare also Mamiya 7 with all LF! 120 compared to around 60 in many cases....Even if 4"x5" has a much larger area than 6x7 it will not help for the result. How should an LF camera be tested? Most likely people will use them for landscape.
