The estimated reward doesn't get reset each round any more. It will continue to grow in real time as you find shares. Whenever the pool finds a block, we will use the block reward, plus the buffer, to pay your shares; when that happens, your estimated reward decreases, and your confirmed reward increases. W're going to be renaming these to "Pending Reward" and "Available Balance", respectively. And there is no longer an unconfirmed reward, since we pay *all* shares, even for invalid blocks.

I agree. We're going to add various things to the round history soon: duration, total shares, total donations, ESMPPS buffer, total reward paid.
