Honestly, it depends on the player and their probability of winning. They all think they can win, but in reality there are only a handful each week with a REAL chance of it. I'm joking a little. But when your player is just lucky to be in the field, I was just hoping to help them have a top 20.
The prep work is only greater if the looper doesn't know the course. If you've been there before, or in my case many times before, then the prep work is the same. At a new venue, it takes longer to map out. In my glory days, we still did it with string and surveyor wheels, so you can imagine what Monday and Tuesday looked like.
Aside from that, it's just another event.
