If you guys have not looked at the spreadsheet that they have put up for review, it is a terrific resource to gauge your bid.
Like they say, it is done manually, so as of my last check, did not reflect the 360 BT bid, or a couple of other 100 BT bids that have come in along with a few smaller ones. But the sheet does list how much Steem each person would get if there was no more bidding. So you can pretty easily slot yourself in and figure out approximate return.
This is pretty amazing! Who else lets you see your return before you commit?
