Ok, we've all heard the deal that the Polar HRMs with the power module have some issues potentially on indoor trainers and rollers. In researching this, I really cannot find specifically what the problems are or peoples experiences so if anyone has any, please share them with me.
Now that the cold has returned to good old North Carolina here, we've dropped back into some crappy temps and given the lack of daylight, it's easier to train indoors. With that said, I've been on a wind trainer and roller and believe my power is reporting higher - often 20-40 watts higher then where it should. Likewise, the jumps can be pretty dramatic, you can 150 watts to 268 in one or two updates of the watch.
Which leads me to the the question: is the 'potential inaccuracy' the jumping around of watts or is it that it runs higher or lower. Any ideas?
