Expanding Diagonal, Wave 5 stops just short of reaching the Wedg

Expanding Ending Diagonal Wave 5 must go beyond the end of Wave 3: No "Truncation".
In Contracting Diagonals, Wave 3 is always shorter than Wave 1,
Wave 4 Shorter than Wave 2, and Wave 5 shorter than Wave 3.
In Expanding Diagonals, Wave 3 is always longer than Wave 1,
Wave 4 longer than Wave 2, and Wave 5 longer than Wave 3.
