30-day Count (Rolling): 0
365-day Count (Rolling): 0
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): -100.0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): -100.0%
Average CVSS: 1.11
Max CVSS: 6.8
