Very true, ~200 ms is a good assumption for the conscious reaction time of an attentive human, but that doesn't mean we perceive time in 200 ms increments and can't tell the delay between "click - 2 ms delay - something happens" and "click - 200 ms delay - something happens". The latter is quite obvious.
