Aircore Weights

Aircore 1 (50 feet) is listed at 1.1 oz. or 31.1 gms. directly beneath the heading. Then a table lower down in the description states that it is .004 oz./ft. which is .2 oz. or 5.67 gms.

Aircore 2 is listed at 1.2 oz/34 gms./50 ft. The table says .01 oz./ft. which is .5 oz. or 14 gms./50 ft.

I assume mistakes have been made in the table re. the accurate oz./ft.?
