Different testing rigor for "good copy vs bad" compared to getting valid MtfMapper numbers?

I would like to add flat target the above list. Folded and then straightened newspaper taped to a wall from two corners is not quite there. And alignment.

You are absolutely correct. I have found from experience that just dry mounting a target to a piece of foam core won't do it.

I'm wondering if you would make a distinction between a "level of attention to detail" that is adequate for "good copy vs bad copy testing", vs a higher level for getting valid, repeatable MtfMapper numbers within +/- 10 lp/ph

Am I incorrect to think that:

Or, is a simpler de-centering test mostly or fully adequate for "good copy vs bad copy"?
