Along the same lines, if you had a circuit that took an input pulse then output a pulse of half the length you could double the resolution (kinda like a one-shot with the output length is half the trigger length). Just send it 2ms-4ms (same frequency) pulses and get 1ms-2ms out to the Victor. The couple ms of jitter induced by changing signals between 2ms & 4ms shouldn't affect the servos or the Victors since they just require a minimum length gap between pulses (8ms for the Victors). This circuit could be installed in the place of the current buffer IC on a future rev of the digital sidecar. Just a thought.
