When the car is right I only use about 60% Dual Rate.
Any more and it's scrubbing and or double-steering.
For a baseline, 100% dual rate is set by adjusting the epa L/R so that full lock is attained, but not forced, i.e. wheels, and any steering bits are not binding, or touching anything.
Loose is fast, some drivers like a car that will rotate hard, i prefer a car that cuts tight arcs, but never brakes loose at the rear so much that I have to counter-steer into a slide.
You're exactly right about the steering throw, setting L/R end points and then dialing it back is what I do as well. 60% seems about right, but the dual steer was still present when I was running magenta fronts before switching to the purple, makes little difference but no matter, I will test it out on practice day.
