The first few transactions are added to the open ledger at the base fee (ie. 10 drops). Once enough transactions are added, the required fee will jump dramatically. If additional transactions are added, the fee will grow exponentially. Transactions that don't have a high enough fee to be applied to the ledger are added to the queue in order from highest fee to lowest. Whenever a new ledger is accepted as validated, transactions are first applied from the queue to the open ledger in fee order until either all transactions are applied or the fee again jumps too high for the remaining transactions. Current implementation is restricted to one transaction in the queue per account. Some groundwork has been laid to expand in the future. Note that this fee logic escalates independently of the load-based fee logic (ie. LoadFeeTrack). Submitted transactions must meet the load fee to be considered for the queue, and must meet both fees to be put into open ledger.
