A few mm up or down is fine. You need to press about 1/3rd more than where you will end up. The problem for me of the over-powered 'bikes' is the backlash on the rest of us. There is a gang of 16 year-old boys on unlawful bikes in my town. They are doing 30 on multi-use paths where there are families, dog walkers and moms with strollers and distracted tots. Most people put all electric bikes into one category. That is understandable. It is going to get shut down because of the over-powered throttle bikes. Those kids don't pedal. All it will take is one maimed dog.
