Payouts are currently scheduled once every 1 hours with a minimum payout of 100 TKL.
There is a limit of ~200 recipients that can be included in a single payout, so the pool payouts are monitored and the min payout adjusted accordingly to ensure a constant flow of payments.
Pending blocks have not yet been scanned by the payment processor. After being scanned, blocks will need to receive both dPoW notarization and 10 confirmations before being actually paid out.
On your worker stats page, pending balance is the remaining estimated amount to be paid for blocks that were scanned but not yet eligible for payout either because of dPoW or min confirmations. Balance includes blocks that were scanned and already paid out but you have not yet met the min payout.*
*Please note these 2 stats will only update when the payment processor runs which is currently every 4 hours.
Payments that show up on the payments page initially are in the process of constructing the z transaction. Once the transaction actually broadcasts to the network, the blocks paid out will become hyperlinked to the explorer and then should arrive in your wallet in the next block or two.
