For typical data requests after the initial resolution window, the resolution bond required for subsequent round doubles with each round. However, escalation games cannot go on indefinitely, hence the need for a final arbitrator as a backstop. This arbitrator determines the final outcome of the request in the case that the resolution bond becomes too large and threatens the health of the protocol. They cannot otherwise affect the outcome of a data request and is triggered when the resolution bond of a data request is equal to 2.5% of FLX total supply (subject to change by the Flux DAO).
