The most optimistic count has limited room until invalidation - the wave ((2)) low must hold.
Two alternate counts suggest a triangle is unfolding. Again the wave ((2)) low must hold.
The final count assumes a truncated wave C of (B). There is more room for downside but once lows are met, wave ((3)) will follow similar to the primary count.
