Does it really save any energy?

Marzocchi's ETA feature lets the rider lower a 100mm fork by about an inch
and
reduce the travel to an inch.
I'm not sure whether the claimed benefit is change in bike attitude, less
energy
absorbed by bobbing, or both.
But thinking about the bogging aspect, it seems like it might be a matter
of
longer travel through less resistance vs shorter travel through greater
resistance. If that's true maybe the energy absorbed is a wash.
Two different things here. First, with the fork compressed enough and a
steady pedaling motion there will be no movement so no energy loss. Second,
the difference in resistance between the two is minimal, the damping
characteristics aren't that different at the two the levels and the spring
rate is the same, just preloaded.
