I think you might be refering to a post I made once explaining the different types of loss in the drivetrain. You have the inertia of the parts you need to accelerate, which will go up with power, and the static losses, or losses that are always there. Like the fluid drag, seal drag, bearing drag, etc. I'm not sure if there is a more technical term for it, but I refer to them as static losses because they shouldnt change with an increase in power. Meaning the loss percentage actually goes down with increased power, though total loss still goes up naturally.

That might be it, not sure.
