New IBU estimation method suitable for Whirlpool and all other hopping practices. You can download the spreadsheet that I made from:
https://drive.google.com/open?id=1EPOTW0mnxaRLFjRPJ9wYci7zWSJf50Gz
More info about the method in March/April 2018 issue of Zymurgy magazine. Enjoy!
Let me know if you have any question or ideas about further improvement of the spreadsheet and/or the method.
