> Not only that but 250ms is the average reaction time of a human, you don't notice an extra 5 milliseconds.
Please stop repeating this sort of thing as a simple fact.
Time and latency are difficult things to reason about and simple explanations sound particularly convincing when one lacks an intuitive understanding of the subject.
Perceived latency is not the same thing as "reaction time".
What reaction was measured? How? From what stimulus?
Your reaction time number does not support your claim that humans can't notice a 5ms difference in lag.
In any case, you are misunderstanding and misrepresenting the comment you replied to.
When you are talking about an organisation like Youtube (size, money, mercenary, malicious, etc.) and discussing metrics like this, individual milliseconds is not an unreasonable unit to use. Consider the volume of the data. Nobody is saying that if something takes 5ms longer to load that no single human being will be capable of waiting for it anymore.
Further, your 250ms is perfectly in the range of the parent comment's order of magnitude of hundreds of milliseconds.
