RE: Spin entry? and Snaps...
Yup pattern rules say the nose must drop. But usually you dont see a downgrade as long as the nose OR a wing drops clearly indicating a stalled condition. Big hits I saw in pattern (advanced, which I judged) were for snapping over into a spin or visibly forcing a wing to drop. As long as the plane clearly indicated a stall by dropping the nose or a wing you didnt get downgraded.
