First of all look on the persons profile when they started. As for me I started in Feb 23,2013 and started out just like most do. Some are better then others when they start. As for me I couldnt hit a large red barn when I started. But It takes lot, and lots of practice I started noticed a very little improvement at 3 months, and I put so many hours into the game. Today I am a Tour Pro close going into a Master but put alot of time into the WGT Tournaments. Your are welcome to come to my profile and click on awards, stats, and score history you will be able to see some of the hours put into the game.
But even when I was a hack I would play Master, Knowing they would win but I could see myself improve over time.
Like I said your welcome to come and look at my profile, awards , stats, score history
