Snap or not (since we have nothing better to do)

[Ed Alt]

I've seen Dave Lockhart and a handful of others do a snap in a similar 
positively loaded condition?  You see a very well defined pitch break a 
clear indications of an autorotation.  I know, planes differ etc, but I'm 
still not buying that as a snap.
