Thanks for the chart, it shows that there is feedback between sidestick position and force that is "local" but that does not provide tactile feedback to the pilot regarding the requested inputs affect on the aircraft.

In the "old school" derived from original direct cable controls (later emulated via artificial feel) the same chart would have opposing forces generated by "artificial feel", harder to push if speed higher or whatever.

I don't have an informed opinion on whether this lack of artificial feedback is a "good thing" or not, just wanting to be clear, in my own mind at least, on how it works.

Despite the lack of "informed opinion" I will guess that feedback might not be that helpfull since the relatively limited range of motion makes this as much as "force" sensor as position. That combined with different meaning of inputs across the laws would create yet another layer of possible confusion.
