Ok I seem to understand this better now, so the player will be "subbed out" at lets say 80% fatigue (assuming I set it to that) and "subbed back in" at 90% if set to that. Very different than the sliders, but this brings me back to the question on the RBs, why have a RB slider to share carries with the HBs? How would this two sliders work in conjuction?
