That’s a question that should be pursued. I haven’t checked the details but I would be a little surprised if the other_xml is modified on every execution, and equally surprised if the statement was re-optimized on every execution. So it’s possible that this will only tell you what happened on the first execution – or maybe it tells you what the expected DOP is, rather than actual DOP, where the expected DOP is not necessarily the degree of any table, or the degree of any hint.

or ist just other xml changed, but not the plan?
