Only a couple of things I noticed, 1) is that the donations are listed as eligible for part "A" share, but donations are only eligible for part "B" share. And 2) I think (?) donations don't get dropped for not mining (their good for the whole round).
Thank you Jake.
Column B check for eligibility (no more than 1 cell=0 to be eligible)
How part A share is calculated:
12/#_of_users (cf cells H3 and I3)
So I can update that very easily depending if donation users are counted or not.
At the moment it's automatic: part A share + 12/#_of_users_except_donation for everyone (cell I3)
I can manually force the "eligibility" to part B to "yes" for donation workers.
