From page 39...
... Based on the results of the test, the performance of the hole-damaged rail section was virtually identical to that of the undamaged strong post barrier section tested at the 17.5 mph impact speed. As a result, the research team has recommended that the repair be initiated if the hole exceeds 1 inch in height.
