Cloud Sailor - not sure if this is what you meant but regardless of revisions, the disputed pairing will always remain disputed unless changed by the SIG. If it goes to another base than it's a different pairing number and thus not disputed. However, take LAX last month - the DP was voluntarily picked up by an FO, it was then revised to get rid of the "disputed sequence" and a nice DH was added on the end. Didn't matter when it was picked up - disputed pairing remain disputed and it was flown voluntarily so that didn't help the process. Correct me if I'm wrong but that's how I've always understood it.
