You are giving too much credit to a single ASIC test board measurement, which was probably done to ease the pressure from the shareholders. The chip can have 0.1J/Gh in a test environment, but as a miner I care about how much power is my miner sucking from the power outlet and it seems that all AM gen3 miners need at least 1.1W/GH (~1.1J/Gh/s to be correct). My Oct/Nov Jupiters are having that power consumption and I mined a lot of coins up until now. Even I know now that chips can be slow-slow, fast-fast etc and I'm not a tech guy. It's obvious that the average chips perform much worse than what was shown more than 1 month ago. Even the blog post has "Tips:this result is not very accurate just for reference." at the end so I wouldn't take that as granted.
