We tested the CPI (DPI) error with the mouse set to 1000 DPI. We noticed that when moving our hand slower, the error from the set CPI was higher than when moving our hand faster for the same distance. We do multiple passes and average them for the final value you see on the review (4.7%).
To give you more details, at slow speed, we got an error of 10.28% (1103 DPI) and at fast speed we got -0.82% (992 DPI).
So i was wondering is developer team aware of this, that mouse have acceleration problem at slower speed?
