There is one wild card - I think the S. Cal mags (like CW) tend to head out and test top speed at deserted stretches of roads on the high desert. So the bikes are running at elevation - not a lot, but perhaps 2-3K feet. This reduces engine power by a few percent.

But there are some mitigating factors: 1) The desert air is thinner so aero drag is also reduced - not as much as power, but the air is thinner; 2) some of the magazines "correct" their data to sea-level conditions; 3) many will do the run in the direction they have a tailwind to get the highest possible number; and 4) the bikes are generally "ringers" - carefully selected by the mfgs to be the best runners of their test fleet, carefully broken in, and carefully tuned.

So, all-in-all, I'd call it a wash.
