Right, "very accurate speed and distance readings even without calibration". But I guess calibration
could help.
But also, according to the web pages, it uses multiple accelerometers and the technology can be used
to tell a bunch of things about your foot positioning - the type of thing that could be useful for
biomechanical analyses. The technology sounded capable of producing reasonable estimates without
calibration, although I suspect calibration might be helpful. But what's actually in this model and
how it's programmed might be limited compared to full strength technology.
The one article was describing how conference attendees walked around with it, one guy tried to fake
it out (he kept notes on what he did and when), and the analyzers got everything right - including
more detail than the guy had in his notes. This might've been a different application of the
technology though.
It would be very interesting tho' to learn if in fact the Polar

yea, and Sat I just put in an order for a S720 with a group - except I don't think they have 6
people ordering (I was the 3rd on the day the orders were due), so I may see if I can reconsider.
Actually, I wonder if they'd be interested in delaying about 6 months until the 625x is available
here
My gut feeling has been that something with hrm, elevation, and distance (in that order of
priority) would be coming out this year. The pieces are there. Although I'm not sure if the mobile
connectivity features of the 625x add significantly to price.
