I have only given a score of 100 to 1 left bank red Bordeaux wine (the 1982 Leoville-Las Cases bought for $34.97 c. 1986 and consumed with family on the last day of 1999) and a few years ago i would have paid a maximum of $160 for such a wine. Today I would pay $170 (haha). For each point down I would divide the price by 1.108, and for each half point down I would divide the price by the square root of 1.108 (1.0526).. Theoretically I would pay up to $36.51 for an 85 point wine, but in practice it would probably cost much less. Things are much worse at the top end, and it is unlikely that I would find a wine scoring above 96.5 points within my sensible pricing guidelines.
The 1.108 was derived as follows: the QPR article of Nov.15, 2006 giving average red Bordeaux prices for 2000-2004 (both banks, but I drink some right bank red bordeaux and equal prices should mean equal quality) gave an average price for 85 point wines of $25 and an average price for 88 point wines of $34. 34/25 = 1.36, which to the power of 1/3 = 1.108 .
Later I did some research into the quality-price relationship going back as far as c.1820 and as late as a study ending in 2014,
but I will refrain from giving details unless someone is interested. The 1.108 worked really well in each case.
