Yes, I agree with the energy analysis, and also an analysis based on cosines of a difference in position of the input and output of the bars. I think I have mentioned the energy analysis myself already. It's the lever length analysis that I can't agree with.
Doesn't really matter ultimately - I have done an empirical test and seen the results. I have seen a few explanations based on sound science. My mind is at rest.
I only asked the topic in the first place because the .047thou bar (~1.2mm) on the B4 behaves in a much softer way than the 1.2mm bar on the Yokomo, and the 1.2mm bar on the Tamiya.
