Only Ranked Stroke Play rounds will affect your average... So play in Ranked Stroke Play, Stroke Play Tournaments, Ready-Go Tournaments, Premium Stroke Play Tournaments, Club Tournaments, etc.
Also, be sure to post every round, good or bad, to make sure your average stays at what it should be, and not what you want it to be. Piece of advice: Rushing to rank up in tiers will only negatively affect your game.
