Hi Cam,
I'm not sure if that's a comment for me, regarding my "commercial item", characterisation, but if so, then I'd still suggest the same, as it's a commercial item forming part of a vendor/manufacturer's standard albeit, low volume products and not a commissioned or contract manufactured/one-off item. Much like Canon or Nikon's $10,000-$20,000+ telephoto lenses, which whilst they may be tested during manufacture, come as a final product to the purchaser, without any objective test report on optical parameters
for that given lens. You can of course go online and get the generic MTF data for that model of lens as a start, but nothing specific to
your individual copy of the lens. "Thanks for buying Canon / Nikon" is about it.
Best
