We can't/shouldn't argue if you can comprehend something, but arguing about if something is generally comprehensible is different.

I was going to point out that in a bull market you are obviously going to make more money by investing a lump sum early (or DCA early) than keeping most of your money uninvested for the better part of a decade, but this comment puts it into context for me. As far as the visualization itself, I am confused why orange is labeled as $15,084 initial investment in the chart but the description says $15,100. I would also like to see the total DCA investment identified, I assume the DCA investments are made on the first of each month but you don't say specifically.
