Sam,

I use PP info and the sheets but I know of others that use the sheets only and some that use some pretty sophisticated pace analysis, etc. along with the sheets and all are pretty successful. It all depends on what you are comfortable with. Sometimes more data does not necessarily mean more information. (Here I am using the defninition that information "reduces uncertainty.")

Also note that often 2 experienced sheet users can come up with very different opinions on the same race so there are a lot of different ways to use and interpret the sheets even if that is all you are using.

Good luck.

Chris
