i'm still pretty new, only been playing for about 5 months, and i catch myself looking back a lot too see if anyone is on our tails. i guess i just want to be considerate, but i think i put added pressure on myself to play faster that i probably shouldn't be worried about because i even do it when there's no where to go in front of us. we usually keep good pace with the groups in front, and usually finish between 4-4.5hrs. our usual foursome includes a 10, a 20, and two 30's so it's not like our whole group is hackin it up. i think i just need to block it out mentally that there is no one behind us because this has prevented me from getting a consistent pre-shot routine. i think it would help with those handful of mis-hits every round which would of course drop a few strokes
