I'm about to buy a Powertap and am trying to find out about the difference between the Elite and the Pro:
On Saris' site, apart from the hub weight and axle material (neither of which I'm bothered about) the only differences are that the Pro supports 'Onboard Analysis' and outputs peak (maximum average) power.
Can anybody tell me first of all what this 'Onboard Analysis' is, and secondly for what would a peak power reading be used? My understanding was that power training was based around Critical Power, which is derived from the average power over a given time period.
