Next reset probability
Insufficient samples or changed cadence; no probability available.
Method
The latest 8 completed gaps between regular events (including needs_review records) are used. Banked resets are excluded. λ = 1 / mean gap (per day); P24 = 1 − exp(−λ), P48 = 1 − exp(−2λ). This memoryless model does not increase the probability as the waiting time grows. It assumes a stable independent cadence and is not an official schedule or a calibrated guarantee. At least 5 gaps are required; estimates stop when the current wait exceeds 3 times the sample mean. Confidence is medium only when CV < 0.5; otherwise low.

Questions about resets
Which events count?
Regular events, including needs_review records, count toward the 66 resets. Banked events are counted separately and excluded from gaps.
Method
The latest 8 completed gaps between regular events (including needs_review records) are used. Banked resets are excluded. λ = 1 / mean gap (per day); P24 = 1 − exp(−λ), P48 = 1 − exp(−2λ). This memoryless model does not increase the probability as the waiting time grows. It assumes a stable independent cadence and is not an official schedule or a calibrated guarantee.
