that is not obvious to me. Maybe it is obvious to you. While I would hardly say that 'low duty cycle/continuous broadcasts' is huge useful, it would allow folks to both pair and connect their sensors and computers without having to deal with (for example) spinning their wheels and cranks to check things out. And I would point out that there IS a duty cycle that makes continuous broadcasting of data irrelevant (pick your definition of irrelevant - unless it is aboslutely zero). The question is the relative power consumptions and marketing trade-offs derived from that.
Plus it would save Bontrager the effort to fix their documentation :-)

Assuming that these sorts of things strongly favor minimizing power consumption doesn't require detailed understanding at all. Especially, considering the source of power and that the transmitters spend a majority of time off duty.
You have no idea if things where really working unless you are getting data (if the wheels/cranks are spinning).
The sensors often get bumped and move too far from the magnets (this is a common issue).
So, off-duty transmissions are very close to pointless even without considering power and complexity issues.
You only (basically) have to pair once. Pk

I think some head units do that.
