Let's say you want to setup a 2 storey house with a CSV1A valve and 20 Gal. pressure tank and 50/70 pressure switch. I understand a 10 Gal. pressure tank is usually recommended in this case, but maybe you want to try and get the best of both worlds and also reduce the number of pump cycles from small demands when the pump is off and the pressure tank is still above its "turn on" pressure, so you go to a larger tank.
So if I understand correctly, in this case it will take the CSV valve 5 minutes to fill that pressure tank (1 gpm) after the last faucet is turned off (assuming the 20 Gal. pressure tank will hold approx. 5 Gal. of water).
What happens if for example the CSV valve is in the process of filling the pressure tank and someone turns a 2 gpm faucet on (when the pressure tank is only partially filled)? What does the CSV valve do? Does it go back to "full run mode" and stop filling the pressure tank, or does that faucet draw from the pressure tank until the pressure switch sends another "turn on" signal to the pump?
