Every devil has demonic powers. Sairaorg just has next to no demonic powers. Even if he had POD, he barely has any fuel source for it which is demonic powers. I never said Sairaorg didn't have any demonic powers. I just said if it was possible to increase the little demonic power he had then he would have done it by now.

And you misinterpreted that statement. It was saying that Rias' ability as a Wizard-type was very high and the increase in the chart showed that. It said nothing about her demonic powers increasing. Her being a Wizard-type is due to her using her demonic powers to fight.
