Do you use the two way volume or directional volume when finding the grade adjustment factor "fg?" Thanks.

if direction volume is given, use it. Otherwise use one way volume. I think all the problems are required to use one way volume, unless specify different.

Any one correct me if I am wrong. I need to know this.
