Handling 14bit values is a non-trivial task. There is no simple way to have a true 14bit reading without excessive noise (of the value) at a reasonable cost in hardware. The magic has to happen in the software. I tried to push this a bit further in the latest release of the Electra Firmware by implementing variable acceleration rate.
My personal feeling is that it has become way more usable and predictable. I still do see ways to improve, however, I am not sure how much priority it should be given. Has anybody tried 14bit controls with the 0.9.12 firmware? If so, any opinions or suggestions on that?
