I work HL and was taught to mark the forward progress spot with my "upfield foot," which is the foot closest to the endzone the offense is driving toward. Depending on where the ball is on the field and the situation with the play, I may come into the nine yard marks to help give the U a better spot. This mechanic seems pretty consistent throughout our chapter, but I don't know how it is done elsewhere.
