Converting this to Power means a power output of 1450W for 25 mins - is this any good? More over, is it likely to be at all accurate?
Exercise power and calorie measurements are wildly inaccurate. There's no reason that such a device couldn't be very accurate, but they aren't. I presume either 1) it's more expensive to be accurate or 2) people like the inflated values, or 3) a little of both.

Burning 500 calories in an hour is a pretty good level of effort, for comparison.
