I would expect roughly 30k to have moved over from the total_vesting_fund_steem figure into the current_supply total.
If you look at the above figures as a snapshot, the supply of liquid STEEM was 2,141,216.341 (current_supply - total_vesting_fund_steem). 30k would be an increase of around 1.4%.
I am definitely going to be pinging you with a few technical questions in the next week or so. You've got a great handle on the mechanics of the Steem model.
