It's not fraction of total energy used, it's the ratio of the original input energy that ends up turning the wheel.
Imagine you had a line of 24 people and you asked them to cross a room with traps that kill 2/3rds of them.
66% of the people make it and for the 18 people who survive, send them round an outside corridor and back to the start and ask them to cross again.
This time 12 make it, repeat.
No more than 24 individual people can ever make it across the room, but even if we stop after a 2nd cycle already we have 30 crossings. One way to express that is that the crossing equal 125% of the initial people input into the system.
We haven't broken physics, were just arguing semantics.
