#2, not to the tips, but if the tee markers are ridiculously short, I'll go a little further back to play it more realistically.
#20 Sure. Say Im inside 80m and I reach for my ever so trusty wedge, I should be able to hit that shot 4/5 times at least on line and within 15-20ft. If I pull it 40ft left, and its still on the green, Im not going to be happy. Whats wrong with that?? 40ft is 3 putt territory for me.
