What should my oil psi be?

Cold start or under revs its up around 80 , 40 cruise, and at a hot idle down close to the 20. Is this normal or it it dropping too far? I mean its not in the red, but Im just curious.

As long as it quickly responds with the throttle you are good. What pump and oil pan do you have?
