Disclosure: I am on the Stryd team.
That is correct. We have a development plan to handle the influence of changes to wind properly, but don't have solid testing data on that yet. We will do our best to surprise you.
There are several other sensors in it, including an air pressure sensor.
Stryd reports unit-mass power unless the runner enters his or her mass, in which case it reports absolute power. We don't yet know which most runners will prefer, but I personally suspect that unit-mass power will be used more commonly because it can be used to set training zones and it is easier to usefully compare the unit-mass power values of different runners.
Right, and based on our testing so far, we believe Stryd would produce the right result in that case.
That's why we are presently planning to cap the initial production round so we can work closely with the first group of 1,000 owners. Our tests with runners have been going well so far, we believe Stryd is at the point where people can benefit from its use, but we want get more data and feedback before scaling up production. Also, the hardware platform we developed is surprisingly flexible. As we learn more from the first owners, we will be able to remotely upgrade their devices. We will do our best to treat our initial supporters right.
Thanks. If enough people see the potential, we will do that.

For instance the device wasn't tested with varying wind conditions. Running into the wind obviously requires more power than running out of the wind at the same pace... I would be very surprised to find that the developers can account for wind speed in the algorithms they use to determine power output.That is correct. We have a development plan to handle the influence of changes to wind properly, but don't have solid testing data on that yet. We will do our best to surprise you.

All other things being equal, a heavier running should require more power to maintain the same pace.Right, and based on our testing so far, we believe Stryd would produce the right result in that case.

That said, a running power meter is a super cool idea... I hope that people continue to develop these devices.Thanks. If enough people see the potential, we will do that.
