Lines built in the 1920s and the 1940s fail on their own. The limits are 1% for that share and 2% for the \"at most\" figure. A simple rule by year built clears 100.0% of the test lines and the model clears 94.7%, so the model adds nothing over the rule. For lines built in the 1940s, the lines the model called not lead were lead 2.0% of the time, against 0.03% overall. No group may be more than 1 percentage point above the overall rate.",
