Wow, that’s quite different than BGGAR’s comparison graph. For $40, it’s definitely worth taking a chance on it, but less hype is a good thing.
I really believe people should take BGGAR's graphs with loads of salt. Unless he's upgraded his rig, which I doubt has happened as he would likely have rambled on about it for an hour or so in that case, it's likely the old one which is not too accurate and has a lot of trail/error involved to get somewhat consistent results. He's using a Dayton IMM-6 mic with a tube coupler. Not the worst rig but not the most consistent either and definitely isn't IEC compliant (and even IEC compliant ones have their share of inconsistencies).
At the end of the day measurement is as prone to human-error as any other "subjective" assessments. Unless someone is as experienced as, say, Tyll was or Crin/DIYAH is - exercise caution.
