Very good lesson. Detailed, no BS. I mean, not very good, excellent.
With pinky, I'm really slow, but I fake with pulloffs and off beat picking. When I was a kid, and practiced scales and all that, It was much stronger and faster.
With ring I'm a little bit faster. The finger to be worked on, because it's covering the most usefull range. Unfortunately this is the weakest finger by human nature.
With middle finger I'm fastest, not nearly as you are, but it's kinda limited to 1/2 step in range. I can hardly play whole step thrill. let alone larger interval.
