In 2003 Geoffrey Crawley was publishing film test results using a microdensitometer scanning negatives of lines of decreasing separation, see attachment of my tracing of one.
On the LHS of this diagram apparently the amplitude (height) of the trace is proportional to the ability of the film to resolve what he calls "overall main subject outlines".
I believe the little peaks at the top corners of the curve on the first cycle are some kind of measure of adjacency effects.
On the RHS of this diagram the amplitude is apparently higher with films having superior fine detail definition.
So Crawley could get on one diagram evaluation of acutance and resolution but no numbers for either.
IDK if this method is used by film manufacturers more recently.
