Does "spot-on" bug anyone besides me?

From today's Washington Post(in an attention-getting context!):
"The hair comes from humans, but it is ethically sourced, of course," Potton said. He was presumably heading off any problems with People for the Ethical Treatment of Follicles. As for the eyeballs, Potton added, "they take individual silk strands to make the veins and get the eyes actually spot-on."

And from
The current economic chaos and plight of average Americans prove Democrat Socialist George Orwell´s comments on the book offered decades ago ominously spot on. He said "[A] return to 'free' competition, means for the great mass of people a tyranny probably worse, because (it will be) more irresponsible, than that of the state." 

"Spot-on" is a Britishism that has begun cropping up a lot. In my experience, Americans don't like Britishisms from the mouths and keyboards of other Americans -- I get mail all the time complaining about "went missing."

I admit, among possible alternatives"right on" is dated, and "on target" probably strikes some people as undesirably warlike. So maybe "accurate"? "Just right"?
