I shall follow your example by choosing to focus on Gary Posner's updated webpage about this case:
"4/23/11 Update: The James Randi Educational Foundation forum participants seem to be beating a dead horse. Even granting, for the sake of argument, that several of the many clues offered by Renier in the Williston case caused the police to zero-in on one particular pit, which turned out to be the correct one, does that constitute compelling evidence that 'psychic' power must have been in play? Considering the number of psychics, the number of cases they participate in, and the number of clues they offer per case, what would be truly unexpected would be for none of their efforts to ever be credited as having been useful!" See http://www.gpposner.com/Williston-forum-reply.html
So, Posner seems to have modified his position from "Renier did not help the police solve this case" to "Perhaps Renier helped police solve this case, but it wasn't attributable to psychic power."
I think he's saying the same sort of thing I said in post 150. In the absence of psychic powers, you'd expect some amazing hits due to chance. She doesn't even have a single amazing hit in this case, and this may be her best case. She seems to be unexpectedly bad.
