I just thought it was an interesting test tbh. I guess it's useful in the sense that you can assess your sensitivity to input lag and delay/etc with a tangible statistic as opposed to just "feeling", but taking this test is somewhat redundant if you have a monitor/GPU/mouse with excessive input delay since the laggy feeling will be harder to detect than if you're using a 144hz/CRT monitor and a mouse with a high polling rate because of the intensity of the contrast between lag in milliseconds.
Your results are very impressive btw jamz.
