Aren't dividends figured in to the historical prices anyway, though? Via adjusted closing prices?

There are several versions of the S&P 500. The version used here is the price index, which doesn't include dividends. The total return index, ^SPXTR[1], does account for dividends.

In theory, but look at the dataset (https://github.com/AgoraOpus/Sell-in-May/blob/master/resourc...) and the adjusted close is the same.
