You assume that all, say, 'bold' fonts have the same numerical weight
values?  That is factually incorrect, especially as some font backends
support more fine-granular weight (and slant and width) classes and values
than the scale we use (which AFAIR was inherited from an old standard).

And please also consider my comment about the number of fonts we examine
when looking for a suitable candidate.
