and we actually did an experiment with a bike stand, digital bike scale, and a couple of cords to visually see (in actual numbers) the way torque is applied by the Shimano drive unit. It wasn't an ass-dyno assumption or a wild guess.
It's simple - with the current firmware, ECO and BOOST do not "self-adjust" like TRAIL does.
Great job! Could you share these actual numbers how the Trail mode differs from other modes (when set to same assist and torq. levels)? And what do you mean by Trail mode "self-adjustment"?
I have been playing with the assist level settings and I would be happy to learn something new. Currently Eco and Trail have been set for long rides to save battery and Boost is like default Trail. But based on your analysis, probably Trail would be most suitable to be set as highest assist level (Eco and Boost to 2 lowest assist levels), in case it does some magical "self-adjustment".
