For discussion purposes, accuracy = precision ... it does not mean shooting to point of aim. Accuracy is how well the pistol groups. I understand what you meant, but it is worth noting.
As has been stated many times, dealing with an issue of POI not matching POA is a different thing than dealing with a pistol that will not group well. I know you understand what the gun is doing, but it makes discussion easier if everyone is using the generally agreed upon terms.

WebSnyper several of us have tried to explain this to him but it doesn't take.
He has sold several guns and kept ones that were less accurate because of his "scoring system" and his inability to shoot said gun accurately. Instead of working and learning a certain guns trigger he quickly gives up and sells it, which is certainly his business.
Like you said(and others have told him) he judges a gun by where the hits are on the target and not group size. A couple of hits in the red part of the target(or blue depending on which target he is using) and the rest scattered around it is better than 5 shots touching but a few inch's from the red zone.
He is having fun but I see him as a buyer/seller more than a shooter. He is trying to buy shooting ability which there are many out there doing the same but he would have been a better shooter buying ammo instead of more guns.
I wish him luck in his retirement and hope he can continue shooting as much as he wants.
