I believe people who want to play for credits will not post good scores away from match play challenges, doing the opposite what people do now, mainly post poor scores not good ones so there averages rise, or not many will play them, so if they are in pro tier no incentive to go to master tier an amateur could do the same just post poor scores so he stays there & lots would play him for credits but he`s a lot better than meets the eye like a wolf in sheeps clothing.
