You are correct, have been a member since 2015, don't think I played then. didn't even realize I had the game till I installed it again, five months ago now ( 150 CDP). I just started doing brackets this month, won 3 first place. I know if I keep winning, it will advance me to legend, I'm good with that.
Winning three brackets is not easy to do. I feel I am progressing well myself after four months on WGT, but I can't and haven't even risked 100cr brackets because of all the restarters and potential cheat software being used out there. Not worth it to me. Have also seen players who linger around in the lower tiers much longer than they probably should to clean up credits in the "softer brackets."
Not saying you are doing this, I don't know you and you seem genuine enough. You conceded the point made regarding your play and acknowledge deserving a promotion. I respect that. You easily sufficient equipment to play and compete even at the legend tier from what I can tell from research and seen among members of my CC with comparable or lower equipment than you. You are already playing a higher quality ball which offsets some of the distance issues from what I can tell from observations made of others playing in the legend tier.
I anticipate my own promotion before long, just don't know how quickly. I don't play brackets though, because I don't want to give credits away to those who are not playing on the up and up.
It is not uncommon to see an occasional low round but when you see one or two names at the top of every leaderboard it starts to look shady. I came across one player when I thought I posted a great score in a weekly tournament, that had been on WGT for less than a month, advanced up the tiers to Legend and shooting lights out scores. Come on, tell me that is not shady. It took me far longer than that just to find a way to deal with high winds, let alone green speeds.
Again, appreciate you being candid, just know I was pointing out "how it looked" based on your profile. There can always be other factors.
Best of luck upon your promotion, but if you are playing as well as you are, the transition will not be as difficult as you think. Am sure you are already possibly playing practice rounds off of the legend tees. I have tried a couple times myself, but it does adjust your strategy but the game can still be enjoyed.
