The tent could likewise be raised with all or some of its storm-guys already staked down, so that once the center pole is vertical, they'll hold it in place while roof-guys are measured and staked. Tentmaster's has recommended this technique in the tent classes I've led at Pennsic. However, the fact that the tent is being handled by a guy-rope rather than by the center pole makes me suspect it's on the way down: if you raised the center pole by pulling on a guy-rope, the base would tend to slide away from the center of where you want the tent to stand.
