130 x 60/9.25 = 843.24 m/hr

Using the formula shown I seem to score just under 3 Watts per Kilo, but my results are from quite a short hill

I know measuring VAM with a powermeter can show an increase as the gradient rises but iom talking about the observed effect(not measured) of increasing the gradient beyond a tipping point
