| Two isolated bad months, neither a rebasing. Food reads 4,755.04 in February 2024 between 464.53 in January and 486.52 in March -- ten times its neighbours, which agree with each other to 4.7% -- and the series carries on climbing steadily afterwards, 491.4, 497.6, 504.8. Alcohol and tobacco has a smaller one of the same shape: 327.44 in March 2022 between 263.83 and 266.86. Both were found by looking at the months either side rather than at the fall, which is why the first pass filed the food one as a base change in March 2024, a month late and with the wrong consequence. | ||||||
