Much like snaps, spins can be shallow or deep. While a flatter spin would more closely resemble a deep snap, a more vertical spin would resemble the shallow snaps performed by most of the world-class pilots. Just because a spin isn't flat, doesn't mean it isn't a spin, and just because the snap isn't deep doesn't mean it isn't a snap. I visualize it like this: if you can draw a horizontal line through the CG of the aircraft about which the aircraft rotates during the snap roll, and this line is not parallel with the thrust line of the aircraft, as long as there was a break before entry, you have an FAI-legal snap. For AMA, if there was no break before the maneuver there will be a downgrade, but not a zero, since the rotation of the aircraft indicates the wing did eventually stall allowing this type of rotation. I've never actually seen how Christophe does his snaps, so I can't give an opinion on that. I have spoken with some people who were at the worlds, however, and they told me there were a lot of snaps that should have been zeroed that weren't. What's good for the goose is good for the gander. As long as everyone is judged the same way, it doesn't really matter.
