jhcolman - it's a QPR if the second digit of the score is higher than the first digit of the price, until you get to the hundreds, in which case it's the first 2 digits of the price.
So a 95 point wine that sells for $44 is a good QPR, but a 95 point wine that sells for $73 isn't.
That was a tongue-in-cheek formula a friend originally applied to Parker years ago, but the good news is, if you're going to buy by points, you can always find someone somewhere who gave high points to a wine. Vino Vixen, where are you . . .?
