stumpy,
I am 100% sure the cockpitweb test does not resemble the real PILAPT cross-bar test. The PILAPT one is joystick back (or down if looking from top) to move the bar up. I've had two goes so I should know. In fact I've asked them (cockpitweb) to consider changing it and they have acknowledged my feedback. Best you don't use the cockpitweb test for that particular exercise or you will do worse than you would had you not prepared for it. Also, relax it's not as difficult as you think.
Hope this helps.
