Pete, according to Matt, sometimes you can see the lifts and headers and anticipate. But usually, there is a trend. Gusts in one part of the course and almost always a lift or almost always a header. You just have to get into it and see what happens. Ex. There is a big lift just before "A" mark or whatever the case might be. Oh, and he always asks his crew what is going on on the course and she always replies with "everyone else is going faster and higher". It always seems to work for me. He plays great "catch up".
