Very good, Ken.
The only point of confusion for me was regarding the efficiencies of different methods of transfering mechanical power . . .
Wouldn't the power lost be 5-10% in the case of spur gears, etc.?
That is, they're 90% percent efficient, with a potential power loss of 10%?
That was confusing to me and maybe others. Otherwise, it's great.

Ah ha! I knew I screwed up some where. It really should've said "Power transferred for each stage of different small parts after losses in friction, heat, etc.". So for Spur gears, they have a 90~95% efficiency because they lost 5~10% in the power transfer. Thanks!
Once I finish double checking the paper (that's why more of you should read it to make sure there's no error in it), I will post it in white paper, then everyone can download it and distribute it to their team members. Then tell them to read it at home and hope that the paper actually make sense and might teach the students something about motors and gears
. I really hope this is useful to everyone.
