I actually liked the article and I think the first image is really informative. I guess my point is the "clock frequency ramp time" is really due to the interplay of a bunch of different control systems, some in the OS and some not. And when those systems get mixed together, in a somewhat uncontrolled way (which is the case for most PCs), a huge amount of variability is the result and that's what the article did a good job quantifying but IMHO didn't make clear. But at the time scales in your plots "how quickly CPUs change clock speeds" is basically an implementation choice. Just my $0.02
