I'm not sure if this guy is for real.
I worked on the project as a contract engineer for the majority of last year until first flight and i can truthfully say that this guy is totally for real and has his finger on a very large number of pulses. So when he says something take it as red. I however have no connection with TVOC or MA now so am free too answer all questions (as long as its not libelous and i know the answers) so feel free too ask away
