My problem is that I when you go from B to lower G# I slip of the black key and I loose my timing for a second. May'be this is because of my old piano with it's horrible action because I'm having to press harder than on a new piano and then I'm sliping.

ohh! You're having problems with life? but this is a piano forum? hehe I'm just joking! anyway, 'd isolate the problem area and work on getting the leap clean, try doing it very slowly accurately, then speed it up very quickly, (faster than you would do it in the piece) see what went wrong at the high speed, and fix it in the slow speed, then when you think you have it test it at high speeds again.



Good luck!
