These numbers don’t seem plausible. Compared to nominal GDP statistics, they would imply negative real growth since 1980. This is incompatible with some periods of low unemployment that occurred since 1980 (eg. the late 90s). It implies that the US has constantly been in a recession for decades. Also conflicts with other hard-to fake stats like increased power generation and freight shipping since 1980.
Edit: found this quote from the creator of Shadowstats that they don’t actually calculate their own inflation numbers, but instead add a fudge factor to the official numbers. http://econbrowser.com/archives/2008/10/shadowstats_res
