That is Leak Tracker. If i remember correctly you want to be in the green area. Unfortunately they just kind of provide ranges, so i didn't find it all that helpful.
Leakbuster is a different program. Gives you much better analysis, training content, etc. But you do have to purchase it. It is a solid program though, has helped me quite a bit.
They just posted a free video under on here under "instructional videos", on playing the turn, and profitable and unprofitable spots to barrel. it's a pretty good video, and will give you an idea of the kind of training content they have in the program.
