EDIT:
TIER advancement is accomplished by playing rated rounds. Quality of play, which affects our AVERAGE SCORE, along with frequency of play, determines when we are promoted...however, it is not exactly known when that will happen. LEVEL points determine what equipment is unlocked in the Pro Shop. The more we play, the more points we earn and the more we are likely to spend.
