Whining about Parker's reliability

Robert Parker has changed wine by adding numbers to ratings. Luckily for me, we both like big wines and so I can buy wines pretty much by the number. Unfortunately, these numbers don't seem as verifiable as one might like. What is their accuracy? Without that, it is hard to think of them as real measurements of anything of importance. Recently Parker tasted some wines he had previously rated. The relationshipe between them is pretty weak. For those that like numbers with their graphs, the p-value is about .5. The lower right point is what Parker likes the best now. But showing the power of the market--I can't seem to find this to buy. Others beat me to it?

Ouch! They were all the same year (2005)and all French, but I think with easily a factor of 10 difference in the prices!

Not to mention that politically incorrectly spelled word, 'relationshipe'. :)
