That's the way all right. I can't tell you much except work on your timing. It has been a long time, but I'm sure you have to wait until the fan <b>just</b> passes you on its way down(or up, I forget), and then look at the doorway you must reach and 'swim' for all you've got. Tap activate like mad and slip through. Even with perfect timing the fan misses you by bare moments. Have fun!
