Figures 2, 3 and 4 in the letter actually display double lift charts instead of simple lift charts as it should be. Notice that the conclusions drawn in the letter are well based on simple lift charts. Figures 2, 3 and 4 in the letter should then be replaced with Figs. 1, 2 and 3 displayed below, respectively.

Moreover, in Section 4.4 of the letter, the lifts for the boosted Poisson regression model before and after autocalibration are actually equal to 1.75 and 2.23, respectively and not to 1.31 and 2.20 as mentioned in the letter. The conclusions drawn in the letter remain unchanged.
