Of course, I don't play "very average friendly" tournaments like almost all players. Is there a possibility that I will progress to champion tour level one day?
Perhaps he meant "a lot of" rather than "almost all". I'm willing to give him the benefit of the doubt on that.
To answer your question, pp37 -- You are going to need to score a lot of 27's or below from this point forward to lower your average to 55 (currently, it's at 56.82). Is it possible? Yes, but you'll have to score better than you have been lately. I see very few scores below 30 in your Score History, and no scores of 27 or below.
