Stage cycling algorithm

[AlexJ]

Does any one know what it is or when I can find it, I have the below from srm
p=([measured frequency-zero offset frequency] x cadence 2π)/(slope x 60)

does it just include 2* at the start taking into account the fact it measure's left leg output and doubles it.

In addition, does anyone know where I can find the algorithm for Normalized power.

Any help would be much appreciated.

The algorithm takes the measured strain from the sensor, finds the corresponding applied force by using the slope and zero offset of the crank. Then, P = 2*F*d*(cadence * 2π/60)
The power meter curve would be obtained by measuring the strain @ known applied forces using weights. This is how a PM is calibrated. I'm not entirely sure why the zero offset of power meters is variable, but I imagine it has something to do with residual stresses in the crank.

Normalized power is calculated by taking the (average of (1s power)^4)^(1/4) for a given period of time. Hope that makes sense.

Thanks For that.
