I was hoping to get some specifics from you when looking at a BEST "impedance match" ~ 1:1 with the cart in use, and if you had figured out some ball-park value which then can be used as point of departure for listening test.
  
It is not the way how I see it. What you are saying might be useful for some who use different step up transformers and try to evaluate how the specifics of a given transformer (DCR of primary, impedance of cartridge and etc…) might impact the results of sonic assessments against another transformer.  I do not do it for a quite a whale, so my take on it is following: to get a phonostage that you like (fully active or with transformer), fine a cartridge that you like, find a proper loading for the given cartridge and the given phonostage. If you wish to change cartridge or phonostage then you need to review the loading but I do not necessary feel that your loading number with one phonostage/cartridge it relevant to another phonostage/cartridge. In some cases phonostage/cartridge are more and in some cases they are less sensitive to loading. I truly do not feel that any rules might be built in there. Sure it is possible to find a pattern in it but the question why would it necessarily?  To play with loading resistor is very simple if one knows what to listen foe. We do it only when we change phonostages/cartridges. How frequently you do it? I do not change phonostages and I try to use my stereo cartridges to be of the same loading. My mono cartridge wants to have way another loading, so I use a different phonostage for it….
