Counts Per Inch? CPI? I haven't come across these expressions before, except for DPI (Dots Per Inch)?
DPI is an expression from the printing world and has nothing to do with
mouse movement. DPI is meant to describe that for one inch of distance
you move your mouse on any surface, the equivalent number of counts are
sent to the PC - resulting in movement on your screen. CPI is the
correct term for this as it actually is consistent with what you seek
to describe with the abbreviation.
