Nope, you're on the mark - that is an interesting approach. Most of my experience has been with desktops, so take this with a pile of salt I've found the effect can be difficult to notice... performance wise especially. Power wise it might be a dozen watts here and there. Even between powersave/performance it's hard to tell - mostly in latency. As a result, I just stay down on powersave. The firmware does a decent job at 'parking' cores and such as needed, and I still get decent boost performance! All that said, in a laptop I could definitely see squeezing out every last bit like this being a big help
