Unless you are meaning you’ve got FTC in your account that have not been cashed out, you do not have any shares unpaid.
When you mine shares and don’t solve blocks, there are no awards from block solves to pay your shares.
The last block solve was paid in full, all shares after that will not be paid, because the pool was not paid for those shares.
“Round Estimate” in the dead pool shows what you would be paid for your shares if another block was solved. It won’t be, and the shares it is using to estimate your payout will not be paid.
For example:
If I were to solo mine, and block solves were predicted for every 7 days, and I mined for 6 without solving a block then abruptly stopped, I have done lots of work and do not get paid…
Sorry if I’m coming off as a bit of a prick, I just wanted to clear that up. ::)
