Why does my 24-105 have a different magnification (macro ratio) from a 105mm macro lens at same MFD?

That's why max magnification needs to be stated as a lens spec.

Yes, I hardly ever need to know the specification for the minimum focusing distance. The maximum magnification, however, is crucial, and cannot be derived from the minimum focal distance without considerable additional information.

Arguably working distance (to the front of the lens) is more useful information than subject distance (to sensor/film).

Absolutely.  I just wrote a reply that states that in many more words.  There's a chance that it could be calculated from available specifications, for someone who's handsome and really talented.  It could also be a fool's errand.
