What double-click threshold should you use?

A very short interval can indicate a repeat event, while an intentional fast click can also be close together. Compare several thresholds and repeat the same button test in another browser before treating the result as hardware evidence. Start around 80 ms for fast repeat events, then compare 50, 150 and 350 ms to see whether the same switch behaves differently at stricter or looser thresholds.
