its like a muscle. if you stop using your arm to lift things the muscles  will become placid and you wont be able to lift as much. same with psi. if you stop using it it will be harder to do what it is you used to be able to do because your psi is well gone placid. however its alot faster to train psi back to its previous levels than it is to get a muscle back to its previous levels.
