LOL - not a single correct number around but plenty of wrong information!
The "caddy" is the function which offers you a club for each shot - e.g. driver on the tee, putter on the green (these being the most reliable propositions, except for the putter scale).
First, there is no advance from Pro to Master, the Tour Pro tier being in between.
I noticed that K is a TP.
There is a certain (fixed) average limit necessary for each tier advancement, and a certain minimum no. of ranked strokeplay rounds. The same no. of the best scores in the current tier is taken to calculate the average, 9 hole scores are doubled. If a player hits the limit with sufficient rounds played, he will advance, the average restarting from scratch.
Yes, the course lengths grow significantly between TP and Master,
no, the green speed doesn't change, it stays "very fast".
The magic numbers for prospective Masters are 67 and 25.
