The box score is the last place a breakout shows up.
Every swing carries information the box score hasn’t absorbed yet. Prophet 9 measures a player’s underlying performance signals over the windows where they become reliable, compares them with his surface line, and flags the gap. When the underlying leads, improvement follows. We proved that relationship on four seasons of held-out history before we published a single call — and our track record stays public so you can keep auditing it.
The picture to hold in your head is below. A player’s underlying signals — the quality of what he’s actually doing on the field — move first. His surface line follows, late, because surface stats need sample to catch up. The shaded area between the two curves is what we measure, every night, for every player.
Before publishing a single call, we validated the signal on 3,278 held-out player-windows across four seasons. Players our signal flagged went on to outperform by +.039 wOBA versus the unflagged — a result with p ≈ 0. The methodology is ours; the result is public.
Reads the most recent form aggressively. Quickest to believe a genuine surge — and the first to be fooled by a hot streak, which is why it never publishes alone.
The blended view. Where the two readers agree, it speaks plainly; where they split, the spread is reported to subscribers as information in its own right.
Shrinks toward the player’s established level. Slowest to chase noise — and the last to recognize a real transformation, which is why it never publishes alone either.
Which signals we read, over which windows, with which thresholds. That’s the edge, and publishing it would erase it for everyone who pays for it. What we publish instead is everything you need to judge us: the validation, the intervals, and a permanent public record of every call.
Trust the audit, not the adjectives.
Two readings of every player: what the inputs say, and what the box score says. The gap between them is the signal.
3,278 held-out player-windows, four seasons, p ≈ 0. The proof came before the product.
Every projection ships with an honest interval, and every call lands on a public ledger — hits and misses alike.
