Thank you for the heads up, it has been a while.
Technically, each 0.001 STEEM transaction is occurring on-chain and needs to be separately valued based on the exact date and time it occurred, so the guidance wouldn't allow aggregating multiple days of activity. See Q&A 26: https://www.irs.gov/individuals/international-taxpayers/frequently-asked-questions-on-virtual-currency-transactions
My practical approach
By the way, the SteemDB website is pretty useful for extracting data on wallet activity: https://steemdb.com/@joshman/authoring https://steemdb.com/@joshman/transfers
