Funny how this exactly applies to instrument playing. Unearned speed only begets sloppiness. The only way to go past a certain velocity is to do meticulous metronome work from a perfectly manageable pace and build up with intention and synchrony. And even then it is not a linear increase, you will need to slow back down to integrate every now and then. (Stetina's "Speed Mechanics for Lead Guitar"; 8 bpm up, 4 bpm down)
