I have a similar setup but controlled manually by hand.
In my experience on single variated, having selected stop points to rev out can really rip super hard compared to relying on foot or spring.
As far as dual variated, I’ve found that if the variator and rear are designed then tuned really well, no manual control can touch it as far as acceleration, but a programmed incremental shift could be as fast as the best roller based setups. But then reliability and getting the correct control software for all terrain conditions would be the difficult part.
The one thing I know 100% is that locked shift points work incredibly well with overbuilt high blowdown rev machines, not so much with average engines.
