Last updated: prepping for the 2026 season.
This document defines how we actually use the Gridiron Edge models in 2026, not just how they're computed.

Using 2025 Hybrid V2 spread bets:

This is the basis for the Super Tier A concept.

Hybrid Weak (all edge sizes):
Conclusion:
Across 2024–2025:
Fade V4's profitability helps separate strong vs weak Hybrid games, but V4 itself remains experimental and is not used as a standalone strategy.
We tier Hybrid V2 bets by absolute edge:
|edge| < 2.02.0 ≤ |edge| < 3.03.0 ≤ |edge| < 4.0|edge| ≥ 4.0 AND hybridConflictType = 'hybrid_strong'For Hybrid V2 bets:
hybrid_strong|edge| ≥ 4.03.0 ≤ |edge| < 4.02.0 ≤ |edge| < 3.0 (optional, needs external confirmation)hybrid_weakhybrid_onlyFade V4 remains Labs-only, but:
Usage guideline:
hybrid_strong.hybrid_weak games.To make the 2026 playbook usable from the couch:
For each Hybrid V2 pick shown on My Picks:
Strong, Weak, or Only|edge|:Super Tier A (Strong + |edge| ≥ 4.0)Tier A (Strong) (3.0–3.99, Strong)Tier B (Strong) (2.0–2.99, Strong)This keeps the highest-value plays front and center without hiding the rest of the model output.
To keep this playbook valid during the season:
sync-hybrid-conflict-tags.ts after grading for each week/season as needed.Continuity Score is a 0–100 roster stability metric built from CFBD returning production + portal churn. High = stable/veteran, Low = chaos/new pieces. It is not in the production Hybrid V2 model yet, but we use it as a tactical overlay.
What 2025 showed:
Soft rules for 2026 (subject to further testing):
These are guardrails, not hard filters. They inform human review of the card and Labs experiments (e.g., re-running 2025 portfolios with low-continuity dogs removed). Any hard-coded model changes belong in a future Hybrid V5 cycle.
We simulated the 2025 official card (official_flat_100) with and without low-continuity dogs:
Baseline (all bets): 937 bets, 59.5% win rate, +13.53% ROI, +$12,676.80 PnL
Removed subset (low-continuity dogs only): 316 bets, 40.8% win rate, -22.04% ROI, -$6,964.80 PnL
Filtered card (dropping low-continuity dogs): 621 bets, 69.2% win rate, +31.63% ROI, +$19,641.60 PnL
Impact: Removing 316 low-continuity dog bets would have improved PnL by +$6,964.80 and ROI by +18.10 percentage points (from +13.53% to +31.63%).
This is Labs-only evidence and not yet a hard rule, but it strongly supports the guardrail: low-continuity dogs were a significant drag on the 2025 official card. The experiment suggests that avoiding these bets in 2026 card construction could meaningfully improve performance.
We simulated the 2025 Hybrid V2 portfolio (hybrid_v2) with and without low-continuity dogs:
Baseline (all bets): 710 bets, 63.2% win rate, +20.38% ROI, +$14,468.70 PnL
Removed subset (low-continuity dogs only): 239 bets, 44.7% win rate, -14.50% ROI, -$3,464.60 PnL
Filtered portfolio (dropping low-continuity dogs): 471 bets, 72.6% win rate, +38.07% ROI, +$17,933.30 PnL
Impact: Removing 239 low-continuity dog bets would have improved PnL by +$3,464.60 and ROI by +17.70 percentage points (from +20.38% to +38.07%).
Observations: The pattern matches the official card: low-continuity dogs were a significant drag on Hybrid V2 performance. Hybrid V2's baseline ROI (+20.38%) was already strong, but filtering low-continuity dogs would have pushed it to +38.07% ROI. The filtered portfolio would have achieved a 72.6% win rate (vs 63.2% baseline).
This is Labs-only evidence and not yet a hard production rule, but it strongly supports the guardrail for both the official card and Hybrid V2 strategies. Avoiding low-continuity dogs in 2026 could meaningfully improve performance across both portfolios.
The official card treats "Low-Continuity Dog" as a hard guardrail by default.
A Low-Continuity Dog is a spread bet where:
continuityScore < 0.60 (Low continuity band)These plays have been a large negative ROI segment in both 2024 and 2025 simulations:
Default behavior:
Manual override process:
Implementation: Low-continuity dogs are flagged with a red "Low-Continuity Dog" pill on the /picks page. The Portfolio What-Ifs panel (/labs/portfolio) shows the impact of dropping these bets. This guardrail applies to the official card (official_flat_100); Labs strategies may experiment with different filters.
We're planning to add Portal & NIL Meta Indices as Labs overlays, with potential integration into a future V5 Hybrid model:
These will initially live as Labs overlays to test their predictive value. If they prove stable and additive in backtests, they may be folded into the core Hybrid model in a future V5 release.
See Data Inventory for current data structures, and Bowl & Postseason Ops for the operations side.
All numbers above are based on historical backtests (2024–2025).
Performance can and will regress. The rules here are designed to:
