Drivetrain power loss figure CANNOT be a hard and fast percentage value regardless of engine output, it must decline at an exponential rate as the engine output increases since most of the power loss is required to get/keep components moving. ie. The faster you go, the easier it is to maintain momentum - less energy loss.
Have I over-simplified my analysis?
Yes. You need to consider friction losses, and the extent to which they vary with power (torque). Inertia/momentum effects would be (I suspect) quite small, relatively). They (friction losses) may be a fixed ratio to power/torque, or not, I don't know.
