So as such, testing the N52 DISA is not as easy, or so I have read.

The annoying part is that you search N52 DISA flaps and most of the time get taken to M54 DISA flap issues - definitely seems that the newer DISA flap system is in general less troublesome, but it does seem that I am sitting with a slightly unusual problem that has probably not really been documented properly or at all.
