That gives charts in nominal vs. real dollars; taxable vs. tax-exempt; and P/E ratios. There are numbers not just colours in each square. And make sure to check out the “Assumptions Graph”.
Should have linked to this in the OP.
I believe they are re-investing dividends? But can’t find that in the assumptions.
EDIT: Just looked closely at the legend on the graphs, and the third box down on the taxable real returns one says clearly that dividends are reinvested, in addition to how inflation, taxes, trading costs etc. are treated.
