On our radar
Grade accuracy tracker
A public record of how grade A, B, and C games have actually performed — win rates, splits by sport, and how the model has improved over time. Transparency is a feature.
Core
Expert grade scale expansion
Expert members unlock a finer grade resolution — B+ and B- instead of just B, A- alongside A. More signals mean more precision. Free tier stays clean at A/B/C.
ExpertSignal
Daily digest email
A morning summary of today's slate — top-graded games, injuries to know, and weather notes for outdoor matchups. Expert subscribers only.
Expert
Injury grade impact
When a key player is out, the grade recalculates to show the impact — "without Acuña, ATL drops from #2 to est. #6 offense." The headline is news; the grade change is the signal.
MLBExpertSignal
Fantasy and DFS signal layer
Stack targets, batter vs. pitcher splits, bullpen availability flags, and projected stat lines for Expert members building daily lineups.

Built to last
Tallybook is a long-term project. Every sport we add follows the same signal system so the experience stays consistent wherever you are. If you have a sport you want to see, or a signal you think we're missing, let us know.
