Bitcoinsfees.21.co just changed something that messed up their recommendation/estimation (at least that's how it looks like) so don't rely on them for now.
What do you mean?
61-90 satoshi per byte is going to take at most 2 blocks? That's not right. The previous estimation was way more accurate than that.
Also they changed the fee range from 10~ to 20~ and just switched to 30~ few minutes ago.
But looks like OP's transaction have been confirmed. /thread?
