The Staggered Advancement variant in Pathfinder Unchained only lists the values for Medium XP advancement pacing, so I just did the math for Fast and Slow XP advancement pacing, and then condensed the chart of values and ability gains into an interactive spreadsheet. I also determined the actual advancement options you had available at each XP tier based on your level and BAB progression.
I'm using this for my home games, and thought it might be useful for others, so hopefully it helps you out.
Please let me know if you find any errors in the data. Enjoy!
