UnverifiedThe author lowered the risk threshold from the initial 50% to 30% because only about 30% of guests cancel and prediction scores rarely exceed 50%, which caused the first version to flag only 1 of 20 guests on the demo morning and miss 4 guests who actually cancelled.74% similarUnverifiedIn settings where the test risk is definable, the naive threshold-selection baseline exceeds the target risk level in about half of the cases, whereas the Learn Then Test (LTT) method exceeds it in only 7.8% of the cases.69% similarUnverifiedThe SAFETY parameter (default 0.80) is a hard multiplier, not a suggested value, forcing the plan to absorb a 20% estimation error without touching the last fifth of the quota.65% similarUnverified某特征族将困难设备风险排名从第37位提升到第7位，Precision@10从0.50提高到0.70，但早期有效预警数量从4个下降到2个，作者据此拒绝了该变更64% similar
