I suppose you could keep trying emergency stops at different settings until you find one where the TV and trailer do not jack-knife, but that's pretty hard on everything.
Currently we use a Prodigy setting of 7.5-8 based more on concerns about TV brake fade on long downhills. At this setting the TV's rear drums are very roughly the same temp as the trailer's during long descents. At lower settings the trailer's are a lower temp and vica-versa.
This setting (7.5-8) is certainly better than 5.5 for emergency stops as well, but I don't know for sure whether it will prevent jack-knifing. That will have to wait for our next emergency stop.

I, too, cannot achieve any wheel lockup on dry pavement no matter where I set the controller. Currently, I set it for "9" on dry pavement and dial it back to 7.5 in the rain on the theory that I really don't want wheel lockups anyway.
