In the video he ran a similar test and had similar results. IIRC his conclusion was that the manufacturer is deliberately sabotaging the performance of powders in order to direct more sales to the higher margin pods.

It's also why he's endorsing a new powder product he was involved in developing: it performs as good or better than the pods.

I don't think the difference in my anecdote was due to sabotage. I think it was the difference between Hippie Bullshit® and Motherfucking Chemistry®
