I'm positive I have a better understanding of these sensors than a majority of the people here. Twas a simple comment as a lot of you over exaggerate or feed off others. (As did I when I started researching)
I also use a Goliathus speed and the only way I can trigger an exceptionally small negative curve is to move the cursor relatively slow (though it's not exactly consistent enough for such claim imho). Moving the cursor fast is for the most part positive acceleration. There is no fall off as with my older Xai or Early G500.
Edit: Then again, there are multiple variables to account for. I'm just talking from a general aspect in reference to mentioned surface.
I'm also not saying it's impossible to perceive a different feel either. There are quite a bit of exceptional changes moving from the early Agilent architecture you referenced.
