very cool. curious to check it out, as was planning on making such a post regarding whether there was a tool or could be developed one that'd account effectively for Steem earnings, values at time of withdrawals, etc.

Steem is one helluva confusing motherfucker in that regards, because everything gets paid into a pool - so how can we track particularly which Steem was earned when and taken out at what capital gain/loss, when the rate is continually varying and there's no way to clearly distinguish which precise unit of Steem was received and withdrawn when...?
