Which risk increases when a Roman ballista firing rate exceeds recommended limits during a siege?

💡 Explanation

When a ballista's firing rate exceeds limits, heat cycling from rapid elastic loading/unloading increases because the twisted cords generate heat with each launch, which degrades the material properties. Therefore cable breakage is more likely, rather than deviation which requires uneven wear, instability needing structural weakness, or inaccuracy from external factors.
