Enum Percentile 

#[non_exhaustive]
pub enum Percentile {
    P95,
    P99,
    P999,
}

How often a gate rejects a measurement that was fine: the percentile of the chi-square distribution its threshold sits at.

Named rather than continuous, because each name is an exact tabulated quantile and a continuous p would need an inverse normal CDF and the Wilson–Hilferty approximation at three degrees of freedom — code a reader has to check, for percentiles nobody asks for. #[non_exhaustive] because it is an input, constructed and rarely matched, so a new percentile costs callers nothing.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

P95

95 %: one good measurement in twenty rejected.

P99

99 %: one in a hundred.

P999

99.9 %: one in a thousand.
