Are you using your stepper drivers wrong? E3D Revo Roto Retested!

Thanks to PVCase for sponsoring this video! https://pvcase.com/ThomasSanladerer
There was something fishy going on with my initial review results of the E3D Revo Roto, and it was all pointing towards Trinamic's Stealth Chop drivers limiting its performance. But is this Trinamic's fault or did E3D mess up the design of the Revo Roto while trying to get it as small as possible? Well, this one includes quite a bit of exploration, so let's dig in!
