How often should the A/C compressor cycle?

At idle, the compressor hardly ever cycles. That is if the car is sitting in a parking lot, idling. Maybe every 5 minutes it will turn off for 30 seconds. With ambient temps at 90 degrees, the temperature at the vent measured by digital thermometer is ~65 degrees.
However if I am actually driving the car, it cycles off every 20-30 seconds, for about 10 seconds. The temperature at the vent bounces from 65 degrees to 68. It almost seems like when the temperature gets too cold, the compressor turns off. But 65 degrees does not seem that cold.
Is it harmful for the compressor clutch to cycle so often? Or is it operating normally and I should not pay so close attention to it?
Thanks,
Rob
