If you use PokerTracker 4, we have included a built-in solution to help you called LeakTracker. It contains a series of videos featuring the voiceover work of AE Jones (Ivey Poker / Leggo Poker) to help explain the optimal ranges for each key stat, how the stat is calculated and how each stat works with one another. You can also view these videos for free on our website - https://www.pokertracker.com/videos/PT4/leaktracker
