Ok let me try to explain all bitcoins flow inside TripleMining so it is clear:

You mine, we make an educated guess about what you might get when the block is found and put it in "Estimated reward".  These bitcoins are not guarantied, we just make an estimated guess.

When a block is found, a new round starts, and estimated reward will be recalculated based on the info of the new round.  The backend process starts processing all shares.   After the backend calculations are finished, the bitcoins you earned from this round are added to "Rewards that needs validation".

After 120 confirmations, the block is definitly confirmed.  The bitcoins from that block moves from "Rewards that needs validation" to "Balance".   You can see these "confirmed" bitcoins in a table by looking at "My payouts".   The "My payouts" table contains the bitcoins gained from each confirmed block you have mined for.  Your balance at the top of the page will include these bitcoins.

When your accounts meets the following 3 rules: a) have a valid payout address, b) amount above "minimum payout" c) last transaction less then 24h ago, the money will be moving away from your balance, into a transaction.  This is the table on the bottom of your screen.  Your Balance becomes 0 at this point.

The money will sit in your transactions table, where we attempt to pay it out.   This table shows when the transaction was scheduled, whether it is still todo or confirmed, and when the actual transaction is done, the money has been payed out and you will see your money in your bitcoin client.

I hope this clears up the flow your money goes through?
