Are the people you are playing selecting Tiger Woods or Super Tiger when they play? If you're playing with your profile character you are at a disadvantage in that case. If they too are using profile characters then you need to play single player to boost your stats.
just before the game starts you can select your player. I didnt realise that you could play with full stats as one of the pros. I always select my own profile. Only got the game yesterday and shooting -2 to +4 depending how things are going. the -25 to -20 for a daily tournament is insane. If you want a game sometime look me up on cowboyz445.
