I have been using the same clubs and the same white tour SD balls, starting at 65c for quite a while and have never had a problem until now.
I played a round on BPB this morning and had a shocker, on the 3rd hole (162 yards) should mean using a 6 iron with my clubs, a left to right wind of 8mph, with backspin, almost full swing, the ball fell short at 130 yards.
I need to explain here that apart from the new clubs and balls I have, which I have been using for quite a while now. I am playing the game in exactly the same way I did the first time I played.
when I first started playing, I did notice that iron shots would sometimes fall short by a yard or two, but not 30 yards or more.
