I’d add “Energy saving / throttling” process and accounted it in another color on the graph (green vs blue), like in “world energy use over” google search. This way you’d have 50% green-busy CPU, and the other 50% available. Unthrottling would reduce green to lesser values, and 100% would always remain constant in absolute value.
