At your link I saw that my point had been brought up in the comments. The 2 amp fuse passing 8 amps for minutes is for sure a problem. I'm not sure about those other fuses, they didn't seem to be far off. And there was a 2 amp fuse that blew at 4 amps after a few seconds which is what I'd expect. I didn't have enough patience to watch all 31 minutes of the video though, I was jumping around. In all fairness I think he proved his point.
