I saw CC had a sale on the ibike pro Gen III. Not sure how this thing is supposed to calculate power accurately when there are no strain gauges recording force. I understand all the physics involved but it seems it doesn't take into account group riding.

There are a number of threads on this. Cliff's notes version is that most users report that it works reasonably well, with some limitations and hassles. Tons of doubters, including myself, who haven't used it.
Also, there seem to be more people who have tried one and given up on it, than with other power measuring devices, which is not a good sign.
Big problem in my mind, even at $500 is price, when you can get a n actual PT setup complete with wheel for $650.

Why spend all that money to estimate power, when a real PM is not much more. I bought a nice used upper model PowerTap for $500 - satisfied customer.

Here's a long article comparing some of the different types of power (and pseudo-power, in the case of iBike) meters.

I had the first gen version of the ibike. And despite some glitches it worked reasonably well. I used it for a few years before retiring it. The thing to remember is that even if it isn't giving you the same readings a PT hub or SRM would give, so long as its consistent for itself you can be reasonably sure of your output in watts. I compared mine with a PT and it was only off a little bit. So worth a try, but if you are doubting already, then just save up and get the SRM or PT.
