There's no way to know/control how much time is spent between the actual "execution" of two consecutive FTDI commands: clock jitter comes from various sources: FTDI FIFOs, USB bus latency + async clock delay (USB HW frames vs. USB stack), various software stacks, multi tasking scheduling, etc. If you need a precise clock, I think you should not rely on bit banging mode at all. -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
