[Sephiroth]

His full sentence says "Speed is also subjective, and depends what you're doing". It also depends what the internet is doing.

You're just arguing words and ignoring meaning. If you want to do that, one of the OED definitions for "Subjective" is:

Existing in the mind only, without anything real to correspond to it; illusory, fanciful

And while we're being grammatical, the OED also says that with 'the' it means a subjective fact or thing. But that's not how Qasi expressed his words.

So now try to answer the OP's question: Which speed test is a true reflection of his speed?
