It's not the mouse tracking system, it's the buttons - they're basically force sensors to give you variable click durations. Just like the high end keyboards have individually adjustable activation distances (a lot from 0.2mm to 3.8mm key travel), the mouse buttons are the same.
So now the click point is based on how hard you push the button, making it basically an analog force sensor. Which if polled at 8000Hz, is basically a low quality microphone.
By contrast, the tracking camera on your mouse is really only about 16x16 pixels wide xnapping photos at 28,000 fps or so to prevent tracking loss (the mouse works by taking photos and seeing how features drift - move it too fast and the mouse stops responding because you've drifted faster than its feature recognition hardware can detect movement).
