However, you could add a button (or link, or whatever) that, when clicked, kicks off code to grab the last n records, do the calculations in a loop, and update the items as you go along or at the end.
SPUpdateMultipleListItems will update a set of items with the same values, which isn't what you want here, but you could use it as a model.
