Software does not cause any discrepancies. This rig and the sensor imperfection could. The result could deviate several pixels. Those tests and SRAV are the most interesting ones that can't be tested with other means available. High-speed SRAV needs a different rig though.

Is there any updates yet? Mainly interested in seeing tests with A3050, AM010 and PMW3310. Also, could you test angle snapping and deadzoning behavior too? A proper test method for this was already provided. You certainly do not need a rig like this, in fact it would be a worse measurement since the errors from the system and the mouse would be counted too. Either build a script with AHK or LGS (or similar), code a program or use a Teensy/Arduino. Doing tests like this with the machine is only taking time from more interesting tests that cannot be conducted by other means.
