And yet the guy above answered quite easily what you could not? Perhaps THAT'S a clue?

I personally believe that you can't infer how easily did "the guy above" interpret correctly your question. Now, the fact that this very question is by experimental evidence harder to interpret and answer than most are (despite not being technically anything esoteric) may be a clue that it's not asked the best way. Perhaps had you reduced the noise/signal ratio as repeatedly asked, even the person you're replying to may have answered quite easily. In fact his posting history shows that that's generally the case.
