Ineptness of Authenticators/Graders

[BobC]

Would it not also behoove TPGs to not keep such accurate notes and records in case someone was to take them to court over their guarantees, or to dispute losses they felt they had incurred due to wrongful TPG opinions? Without such notes and evidence it would be extremely harder to prove fault in the case of giving an opinion. Kind of like scrubbing a crime scene so the actual fingerprints are gone.

Another reason I had heard in the past for why TPGs may not want to share all specific details as to why they graded a particular card as they did, is to not let card doctors and alterers know exactly what was found or seen so they could improve their techniques and work to better fool TPGs in future attempts at getting their altered cards past them and graded as high as possible.
