If a typical derailleur requires 20mm cable pull, don't know myself, then I would design it so the servo gives around 25mm. Will make your life so much easier not working up against 2 hardware stops, the derailleurs and the servos. You will have more freedom to adjust the end stops in software.
On the other hand don't make the pull too big or you will loose accuracy and torque as the percentage of the servos travel used reduces.
