I feel obliged to meet the demands of the community therefore I've configured a Shimano 3N-80 for a speed test. I've began initial testing and you can see the results below.
(please discredit the Vdrop for now, I need to get my meter closer to the load)
This time I have an e-Werk and like ConRad I found the same 2.75w limitation.
Feel free to provide your critique on the method used to calculate any of the figures.
