While the time between the pulses may move around a bit, this causes 
no problems to a servo.  It is the pulse width of the pulse that 
matters, not the period.  That said, with analog servos a faster update 
rate (period) makes them stronger, a slower one makes them weaker.  I've 
experimented with this and found that you can't make the update period 
too fast or the servo will jitter.  When going slower however what 
happens is that the servo will weaken until it does not respond any more.
