- [[0,0.003,1,0],[0.2,0.004,1,0],[0.4,0.004,1,1],[0.6,0.004,1,1]]
- Method label
- WCAG2.1 event-count worksheet; flash detection supplied
- Maximum general and red flash counts in a half-open one-second window
- [4,2]
- Event-count review flag
- Event count requires specialist review
- Largest supplied affected event area (steradians)
- 0.004
Try another scenario

- [[0,0.003,1,0],[0.4,0.004,1,0],[0.8,0.004,1,1],[1.2,0.004,1,1]]
- Method label
- WCAG2.1 event-count worksheet; flash detection supplied
- Maximum general and red flash counts in a half-open one-second window
- [3,2]
- Event-count review flag
- Event count alone does not establish conformance
- Largest supplied affected event area (steradians)
- 0.004
Calculation method
Calculation method
Maximum general and red flash counts in a half-open one-second window
Sliding window counts independently by already-classified flash type; timestamps at exactly window end excluded.
Event-count review flag
Flag more than3 qualifying flashes in any one-second window. Area exceptions require concurrent spatial measurement and are not automatically certified.
Largest supplied affected event area (steradians)
Maximum event area, not combined concurrent area; no automatic safety or WCAG conformance determination.

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Count user-supplied already-qualified general/red flash events under a declared WCAG2.1 event-count convention. Does not detect flashes from video, combine concurrent visual-field areas, apply red chromaticity tests, or certify safety/conformance. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification.
