The 13k sample rate of the sensor helps the mouse determine movement before that movement can ever be sent over the USB/wireless connection. So in this case, the mouse takes 26 samples to determine 1/500th of a second of movement. Makes sense to me. Doesn't mean the mouse isn't a piece of junk.. I'm just saying that the 13k sample rate should not and can not be tied to the USB transfer rate. They are two entirely different stages of the process. I'll lay it out in simple terms: Step 1: Take samples at 13khz sample rate Step 2: Determine movement from those samples by comparing ~26 samples Step 3: Send movement to computer via USB connection (500 hz transfer rate) That said, this article does read like a company propaganda piece.
