The cycling behavior is the classic symptom of low freon. It is not possible to say that the low pressure reading has a "standard" value, since it varies as a function of other system parameters (temperatures, etc.). It should only be used as a rough diagnostic. The only way to positively know if you have the right amount of freon is to evacuate and recharge with a measured *weight* of R-134a.

I would suggest that you add a small amount of R-134a and see if the cycling stops. If so, you probably have an evaporator leak.
