I don't believe it has anything to do with Promotion.
The green putting meter aid (or crutch as I refer to it) is called "Putting Power Tip". It is essentially an aid that shows you how hard to hit the ball when putting. It can be turned On or Off in the options. It only works in some types of games (Coin Rooms, Scored & Practice Solo Ranked Rounds and possibly in others(??))
It definitely does NOT work in Country Club or WGT Tournaments and may not work in other types of games(??) In other words, NO, it is NOT available all the time.
In my personal opinion, once you get to a certain level you should probably turn it off in the options and rely on your own knowledge and skill, especially if you plan on playing in a lot of games where it will not be available anyway.
