Yes the spikes mess with your data, power curve mainly, but 1 sec at 2000w is not going to up my TSS any because I'd need to maintain some time at that power. In a 2h30 ride those only formed then than 20 seconds or data points randomly scattered. Secondly - you cannot tell me its overreading TSS when the score it gave me was 92. You try do 1300m of climbing on a mtb in basically 1:30 if you exclude the zeros descending and see if you get a TSS under 100. I have done similar ride that it reported at 54 TSS etc...at 92 it was already being generous. My point is not that I'm trying to kid myself with TSS scores, but rather that your assumpsion that the powercal would overread for all athletes is incorrect. I have a resting HR of 30 and max of 170. I fall outside the "Norm" that this equipment was designed for, a large % of time I use it it reports that I am not pedaling at all, when I know by feel that I'm doing around 200w. I initially tested this unit in conjunction with my quarq running seperate recievers per power unit, and sent my data for various rides to the supplier and manufacturer begging them to allow calibration for this very reason. MY charts when overlayed where vastly different and not the vague following trend as advertised or seen by many other athletes with normal heart rate values. This is not a flaw in the unit, in fact its a superb heart rate belt, it was just designed to work for 90% of the people that didn't include me.
