I chatted with @virtualgrowth on discord about it and I'm going to do some blockchain data mining to audit all votes and payments on the accounts to sort this whole ordeal out.
I feel the best approach from a data integrity angle is to go through the entire blockchain for that period so that any changes in vote % etc will be included. It will probably take me a few days to write the script, gather the data and then make sense of it all.
@virtualgrowth has agreed to payout any missed payouts discovered in the audits.
That's kind but already got @Walden on it. I'm sure you're good but I apparently he's 'the man'...
