Cellar Tracker scores show bias patterns according to data analysis

Source: 1 of 5 charts in the analysis from The Wine Gourd

“This Weibull expected distribution is compared directly with the observed frequency distribution in the next graph. In this graph, the blue bars represent the (possibly biased) scores from CellarTracker, and the maroon bars are the unbiased expectations (from the probability model). Those scores where the heights of the paired bars differ greatly are the ones where bias is being indicated.” — The Wine Gourd
