The second bar is just a case of slowly increasing speed using a metronome. Start at a comfortable speed, then increase by 2 BPM, then decrease by 1, then increase by 2, decrease by 1, and so on. That's the method promoted by Anders which I've tried with success (although I tend to use higher increments).
Good luck with this. It's damn fast
Thank you for the advice. My mother always say that I was an impatient person. Maybe I should sit down and practice patiently more
