I've seen the analysis…

The effect is most noticeable in your small cog, where pedalling inputs have
the least impact on your rear suspension. Up on the large cogs, it's only in
the neighbourhood of 4-5%, depending. I also don't think this accounts for the
drop in leverage that you see due to the larger diameter chainring (less
leverage=less force on the chain=less effect of pedalling inputs).
I'll stick with my original statement that I don't think a two tooth change is
going to have much of a (real world) effect here.
And the cases look worse (generally) as you move down to a smaller chainring,
not the other way around (as Wayne pointed out).
