Spur gears and sprockets and chain are both very efficient if built properly -- as high as 98% or so. That means that 98% of the energy input on one end comes out the other.
Losses due to inefficiency occur at each stage of gearing -- so a system with two stages would be ( .98 * .98 ) efficient, for example.

Cool! and... disheartening.. but, with 96% effieciency, that still falls within our range which is about a 75% wiggle room.
