Mats Lewan told me that his video cut off prematurely, but he thinks the total draining time was about 3 minutes. He measured the collected output as 22L.

If it was 1.3 minutes it is more likely 2 Bars, if it was 7 minutes it would more likely be 1 Bar.
My final conclusion is ... at 3 minutes, it's too close to call.
