EPG 620.11.5 is about acceptance for reflectivity readings from a handheld retrorelectometer. The third bullet point down states if four or more readings within a segment are below the minimum value required, the markings are rejected. Under that statement is a "Pavement Acceptance Chart". The problem is the chart does not show the "minimum value" for the markings as per the 620.10.2.4. The minimum value is actually 195 for Yellow and 270 for white.
