Hello San Fran Sam,

To the best of my memory those hardcoded data are the values that were originally calculated for the maximums and minimums in the ranges in the first iteration of the spreadsheet. If you take a look at the top of this post describing rescaled range analysis you will see that someone pointed out an error in my calculations in the spreadsheet. In order to show the readers of this piece the difference that made, I hardcoded the old (mistaken) values to the right so as to eliminate confusion for those that had different versions of the spreadsheet.

I hope that helps!

Jason
