You can find it directly here.
That “Worth It?” spreadsheet came out of my original forum post Spreadsheet: Best Tix to Buy to Maximum Savings on AP Upgrade which links to my sheet that calculates the best discounted reseller tickets to buy when you plan to upgrade to AP.
There’s a version of the Worth It? sheet still embedded in that Maximum Discount sheet, but the first link above goes to a free-standing version where you can enter all your info in one place.
