In this tutorial, I demonstrate BacktestIQ - the tool that finally separates skill from luck in your DFS strategy! Watch me take actual lineup builds and strategies and run them against real historical contests to reveal the true results. No more guessing if your approach actually works - see exactly how your strategies would have performed on past slates with real data. I'll show you how to test different build approaches, and quickly identify which strategies have genuine edge versus the ones that are just draining your bankroll. This is game-changing for serious DFS players who want to make data-driven decisions instead of relying on gut feelings. Stop throwing money at strategies that don't work - let the historical data tell you what's profitable!
