TPAs are useful independent opinions (It's wrong to say they're useless), but they are only one piece in the puzzle. Sellers and collectors should be using them as second opinions, not as the only opinions.
I think most people on Net54 know and do this, but clearly not everyone in and all segments of the hobby do.
