Notice in all of those references linked above that none of them tell you any thing about what will happen in the frequency ranges you can actually hear. That is not to say that the resonant frequency matching should be ignored, but it certainly tells us very little about how the particular arm/cart combo will sound like.
For example, there will always be vibrations in the arm and how these vibrations are ultimately handled has a great deal to do with the bearings and other parts of the arm. How well the arm/cart, and don't discount how important the base this is all mounted to is, deal with these vibrations will be heard while you play a record even though the RF calculation says you have an ideal match.
Then we get to the phono stage and the cartridge interaction. Perhaps you have heard people talk about fast and slow cartridges, as well as phono stages. A.k.a, slew rate. This is a reference to how quickly a component can produce a very low note and then transition to a very high note. A slow cartridge with a fast phono stage can sound rich, syrupy, etc. A fast cartridge with a slow phono stage can sound harsh, edgy, a little distorted.
That is the unfortunate thing, it is all important in the end.
