Squatch031: So my question is, at what point is one considered a good golfer? Is it the Master or Tour Pro at level 120? Is it the Champion at level 130 using spreadsheets and charts?
First off, the levels are but signs of industry - you've played so much to accrue a lot of eXperience Points - XPs.
In the "traditional" average system, becoming a Legend and dropping your average to 61 certainly is a sign of quality - you play as good as any Tour Master, without their "handicap" bonus of a shorter tee box. From there, raising through the tiers distinguishes the better golfers.
I have no experience in the "head-to-head" world to know a "good golfer" there. Is it coins? Is it apparel? Any ideas to that side?
