For any measuring distance between the alternative measuring distances set forth in the following tables, the prescribed foot candle level above ambient light must not exceed the interpolated level derived from the following formula:
[l2 = (D2<<2>/D1<<2>) x l1]
Where l1 = the prescribed foot candle level above ambient light for the measuring distance listed in the tables, l2 = the derived foot candle level above ambient light for the desired measuring distance, D1 = the desired measuring distance in feet, and D2 = the alternative measuring distance in feet listed in the tables, as follows:
