An important aspect that I think is overlooked: even if the latency is so subtle that it's overlooked, subconsciously you may have a feeling that something is off, your perception of the product will be worse, you will perhaps become frustrated without even knowing why. A person I know was diagnosed with tinnitus. And it (the diagnosis) made him happy. For over a year he was frustrated, nervous, but he didn't know why. Turns out he was hearing noise all that time, but just didn't realize it. Sounds (pun not intended) ridiculous, but that's how the mind works.
