We don't have that data. All we have is conversation from former captains saying it didn't work.

EDIT: Also, IIRC, the most successful captains in the field didn't actually use the AOB method of determining the target's course. They would instead cross in front of the ship at a distance. When the ship's masts lined up they knew the ship was pointed directly at their current position and could calculate from their current bearing and the bearing to the target exactly what the target's course was.

In hindsight what the Brits should have done instead of odd paint jobs is offset their masts by a few degrees.

But does that mean dazzle doesn't work at all, or does it mean a successful counter existed?

It's more like the British made a counter to a process in the German manual, but the Germans weren't using that process anyway.
