I've been breaking in a new (for me) used PowerTap SL. Only had a few rides with it, but am enjoying it alot, especially seeing how my power spikes into 500W-ish every time I stand briefly to go up a modest incline. I'd never equated how much more wattage even the merest hill required, especially when you're trying to maintain your speed on them.
I've downloaded the data from the two rides into PowerAgent, and was reviewing the data. I noticed that the average power for the ride as shown in PowerAgent consistently discounts the average power as shown on the PowerTap computer, by approx. 30 watts. For instance, on a ride along the beach today, my PowerTap recorded about 220W avg, but the PowerAgent showed only about 190W avg. I played with the smoothing and sampling factors in the software, but I still get the same discrepancy. A review of the intervals of the ride, as shown in the computer, seem to back up the 220W average. Any thoughts as to the discrepancy?
Also, I am, of course, contemplating taking everyone's advice on the forum to acquire the WKO+ software. Is anyone aware of any discounts/coupons on the software? Is the $99 price standard?
