We received reports regarding the Ultra Tachyon board's polling rate not being accurately measured above 1,000Hz. After re-analyzing the source code, we have optimized the output to ensure a stable 8,000Hz performance.
Note on Measurement Tools: Programs like cakama3a or x-input polling, which were mentioned in some inquiries, measure the packet transmission intervals of a gamepad's analog sticks. Since the Tachyon board does not have physical analog sticks, these programs cannot provide accurate measurements. (Those programs are best suited for testing standard gamepads equipped with analog modules.)

<Existing Tachyon V1.00 measurement data: values are concentrated around 1K–2K>

<Tachyon V1.01 measurement data: values are evenly distributed up to 8K>
