Heh... yeah, that's right. Jay did the Wok thing and all that.
The original WSM, and a feature I maintained, was the ability to move the charcoal grate up to the lower cook grate position and then grill on the upper grate. It was in the original manual from the Erich Schlosser release and they felt it was important to have that on the 14/18/22 when I designed, updated them. If they changed it since 2008, well possibly.
I have grilled on a 14 and 18 WSM with favorable results. I mean after all, it is just heat.
As for the specifics and someone looking for a magic number (5" away with such and such charcoal with the sun at 18degrees during a full moon) well.. Have at it.
Thank you for the clarification A-T-S! I appreciate it.
