It's a long time since I did this, but 200ms is more like it (might have 
been 100ms).  You need  digital clock that is, itself, synchronised, and 
you match the rhythm of the ticks, then let one of them actually move 
the return key.

You have to really believe in setting accurate time not just be 
following some instructions, to do this.
