Spot on! Sort of

"You're 5'9", 5'10"," says the University of Maryland researcher, looking at the computer measuring the man's height.

"5'10", that's spot on!" says the amazed BBC reporter.

Wait. That's "spot on"?

I don't really know how accurately these computers will be able to id a person ambling through a crowd, but a 2" range on a person's height is not very accurate.

And that reporter should realize that. Credulity and amazement, a willingness to be convinced, do not good science reporting make.
