A great thread David.
Whilst I am not really qualified to comment on Tour Legends as I am only a Tour Pro (well playing like one) I do not think one can read to much into the averages at any tier as once saturation is reached, the average only can go down.
However to make TL you must have played with a certain amount of skill - and virtue of the "average" you have proven this.
I have played with quite a few TL's - the top ones all have one thing in common - they put brilliantly. Knowing your distances, spin, shot choice and where to play the approach to all helps but things still go wrong for the best, whether it is a WTF shot, meter issue etc, and draining those 20-30 footers consistently make the difference IMO.
For me the key to this game is not your tier or average, but how much enjoyment you get from it. One day I may join the club and bring the TL status into disrepute, but I will guarantee that I will continue to have fun and enjoy this game regardless of my average.
