comparative lengths of ranks are not meaningful, so distorting them by making bar lengths rank n+2 does not take anything away. In fact, it likely restores the comparative lengths to closer to their nominal values. For example, if rank 1 had a nominal value of 100 and rank 2 had a nominal value of 120, the ratio of (1+2)/(2+2) is closer to 100/120 than 1/2 is to 100/120. I would imagine this might typically hold true for most of the distributions of nominal values within the categories in the chart.
