The factory test pilot was required to demonstrate a safe landing under available crosswind conditions using NO crosswind compensation (= very ugly).
I don't believe that's the case, Dirk. The test pilot isn't required to find a limit, but there's nothing in AC23-8 to suggest that the test pilot cannot use standard techniques for crosswind.
This came up a while back and I posted a link and some extracts here.
