In defence of prices yesterday - the people who would use a tool like this the most are the traders since they are looking at the numbers every day, so it probably comes out of the trader community.
Real returns are expected to be in the 2-8% range which means that most people should be looking at timeframes around 10-50 year. Unfortunately at that range the money printing has a real impact so the chart needs to be adjusted for inflation and, realistically, changes in the money supply [0] and so it is more work for the implementer.
[0] If it hasn't gone up 33% since 2020 it probably lost value in real terms.
