I know, it's great isn't it!
The one thing that CJ says that does make big sense is that all the people we know (Sussex / Surrey and now us) will have used these rollers, so as a group it will give an equal comparison.
But, you can imagine the conversations if you were at either as follows:
At Power Engineering: Yeah, Surreys rollers are ****, their torque figures are always 10-15nm down on true figures.
At Surrey: Yeah Power Engineerings rollers are ****, their torque figures are artificially high.
6 of one and half a dozen of the other I think
