I really dislike this "not cleared means you don't know how to do it"
that is clearly wrong.

I haven't cleared T5 or Titan ex, nevertheless I know what I am supposed to do when. Twisters still confuse me a tiny bit, but still I know how and where (not) to run.

Than there are those that payed for their clear, so they have a clear does it mean they know what to do? Not necessarily .
