alosso: it would take me forever to become a TL.
Note the subjunctive - it's no problem for me, as I have accepted my status as a given fact. I had a blog post until recently accepting "to stay a mediocre Legend forever".
I have no ambition at all to tier up. I'd have to spend money in the top equipment, time in mapping clubs and making notes about the tracks, more time learning to safely hole the ball outside 6 feet, time and money (balls!) to become better. I rather am on the real track and enjoy (rare) birdies with the whole body instead of forefinger limitation ;)
IMHO, the concept is o.k. from a business POV. How many balls and credits are burnt to reach the level for coveted equipment, how many more to get the average down (you named it!) for the next tier? How many players really know why, and what to do then?
To your health, Sweets!
