Pump and tank question

I have a 1/2hp jet pump in the basement hooked up to a WX-202 20gl(total volume) well-x-trol tank. In there sizing chart is keeps referring to a minimum 1 minute pump runtime, when mine runs is for 30 seconds or so. I have the right size tank as per the chart and my pressure on the pump and tank are right. Should I be going to a larger tank to get the right pump run time.

Thanks

If you would like to keep the same equipment but keep the pump from cycling, take a look at the Smart Tee by Flexcon.
