With more teeth/roller contact friction increases
Agreed.
The only advantage to this is reduced chordial rise, but chain wear increases. The chain will run slightly smoother.
Agreed. But we’re talking performance not wear issues.
#1 is true, #2 and #3 need clarification, #2 are you talking about friction, if not more force to the chain is a good thing. #3 the axle sprocket imparts torque in relation to the front sprocket it does not act alone.
2 and 3 are in comparison to a bigger driver/sprocket pair. I agree with your comment.
Larger is a weight increase, flywheel effect only applies to run down time, accelerating a weight and maintaining it's speed consumes energy, although they do store energy, no gain while engine is pulling. Less unsprung, rotating mass is always a good thing.
I think you agree the larger driver/sprocket combo consumes more energy in acceleration, and has higher inertia at equivalent speeds compared to a smaller pair.
this is a fictious force that acts away from the center point of a rotational object, what role does it play here, you could increase it by 200% it will not make you faster
Very good, it is a fictitious force, which I used to highlight inertia differences, but did I imply it makes you faster?
Show how you arrived at the sprockets producing these energy quantities and why did you add them together. Just not enough information to make an conclusion.
This is good place to start your own comparisons:

Thought experiment:
Let’s say we could run a 10T driver and a 10T sprocket vs. a 100T driver/100T sprocket-both 1.0 ratios. Still think the performance would be the same? I think it’s very myopic to conclude that the analysis of drive train performance simply stops at the ratio.
Agreed.
