When someone tiers up, before his first ranked round in the new tier, his last average of the previous tier will be shown, e.g. "Master 66.8". The first game in the new tier will be the start of a new average from zip, as WBW stated, e.g. a 36 (your first) will show as a 72 "average" of one round. From then on, the former scores and average will be history, (partly) visible in the scoring history.
Those interested in average development are well advised to note the overall no. of ranked rounds from the stats in their profile after tiering up.
