I'm still waiting for the 2015 audit....the dates you reference are jumbled up. It started with a 2015/2016 audit uplist that turned into a 2016/2017 audit uplist that turned into a 2018 audit uplist that turned into a 2019 audit uplist.
It has been argued that the 2015 audit wasn't done and it has been argued by the same people that it was and had to be done.
All I know is that it has been "audit uplist soon" bullshit for over more than 3 years.
