the queue will only shrink due to payment limit shenanigans or manual payouts.
Or transaction fees.
Umm this is a official confirmation that the fees are not awarded to shares but used to pay and thus reduce the overall pending balances?
Since yesterday the qeue has gone up and down so probably it is stable at 190-200BTC with fees reducing the queue a little bit over time (it varies from block to block, but the average is around 0,10BTC per block)
