Normal clicking=65, jitter-clicking with my left hand holding the mouse=99
£5 logitech B100.
Can't jitter click with anything like a useful mouse hold. Used to be able to destroy my mates in International Track and Field on the PS1 with jitter clicking - only worked if I sat with the controller on a bed or sofa; jittered with my right finger on one button, held my left finger stationary over the other, which hit it on the bounce-back from the press of the first button.
