The mobile app is built for quick decisions on tonight's slate, so we feature one window per model: 30 days. It's recent enough to reflect current form — rosters, schemes, and rules shift every season — and long enough to mean something across a typical model's pick volume.Behind the scenes, our Top Picks selection uses every window we track: 30/60/90-day, rolling 100 and 500 picks, and lifetime. So even though each model card shows one number, the picks we surface have already been filtered through the full performance picture.Want to dig into the other windows yourself? They're all on the web app — every model's full performance history is there.
