Apart from the strangeness of the results from Brands Hatch, I think generally they got the hang of it. Mine was tested 2 or 3 times at 47-48bhp, which ties in well with the results on Dave Wood's Dyno. I am sure he tested Senna's bike at about 51bhp as well, which is within 2bhp of what it is. Yes, Neil's result seems odd... but it might be that it is right (and we don't test torque, which is clearly more important)
