Across the full 2025 NRL season, Alphr's NRL predictions recorded a 61.5% strike rate on Head-to-Head picks (131 wins from 213 tips). The Margin Band model hit 60.4% (129/213) with a +14.8% ROI ($3,148 profit on flat $100 stakes). The Total model achieved 53.8% (114/212). These results are recorded transparently on the site with round-by-round history. Round 19 was a perfect round — 7/7 correct picks.

Question 3

How does the NRL prediction model work?

Accepted Answer

Alphr uses a 4-model XGBoost ensemble with ~160 engineered features trained on 15 years of NRL data. The Alphr NRL prediction system is a 4-model XGBoost ensemble. It includes: (1) a Win Predictor (binary classifier) that outputs home-team win probability; (2) a Margin Predictor (regression) that estimates the winning margin; (3) a Home Score Predictor and (4) an Away Score Predictor (both regression) that forecast each team's score independently. The ~160 input features include custom team and player ELO ratings, rolling form metrics, venue advantage, weather data, referee bias modelling, positional lineup strength, and Sportsbet market odds. The model was trained on 3,000+ NRL matches from 2010 to 2024.

Question 4

What is 'edge' in NRL tips?

Accepted Answer

Edge is the difference between Alphr's model win probability and the bookmaker's implied probability — only picks with ≥7% positive edge are published. In sports prediction, 'edge' (or 'value') measures how much smarter the model is than the market. It is calculated as: Edge = Model Win Probability − Bookmaker Implied Probability, where Bookmaker Implied Probability = 1 / decimal odds. A positive edge means Alphr's model believes the true probability of winning exceeds what the bookmaker is pricing in. Alphr applies a ≥7% minimum edge filter for NRL, so only high-conviction tips are published.

Question 5

Which NRL markets does Alphr predict?

Accepted Answer

Alphr predicts three NRL markets: Head-to-Head (outright winner), Margin Band (1–12, 13+, or Draw), and Over/Under (total match score). Alphr covers three NRL betting markets. Head-to-Head (H2H) tips predict which team will win outright. Margin Band tips forecast the winning margin range using Sportsbet-style bands: 1–12 points, 13+ points, or Draw. Over/Under tips predict whether the combined score will be over or under the bookmaker line. All three streams pass through a ≥7% edge filter before being published.

Question 6

When are NRL tips published each round?

Accepted Answer

Alphr NRL tips are published before the first match of each round, typically by Thursday evening. Tips for each NRL round are generated and published before any match in that round has kicked off. This prevents any post-hoc selection bias and means every published tip is verifiable as a genuine pre-match prediction. The site updates automatically, and all tips remain visible after the match with their result — Won, Lost, or Pending — recorded for public accountability.

Question 7

How do I read NRL tips on Alphr?

Accepted Answer

Visit alphr.com.au/nrl, select a round, and view each tip showing the team, model, predicted edge, and result. Navigate to alphr.com.au/nrl and click any round tab to see that round's tips. Each tip card shows: the two teams, the market (H2H, Margin Band, or Total), the Alphr pick with edge percentage, the bookmaker odds at time of tip, and the final result once the match concludes. The Season Stats tab aggregates wins, losses, ROI, and strike rate across all published tips for the full season. Each match also has a dedicated detail page at /nrl/match/[id] with deeper model breakdowns.

Question 8

What features does the NRL AI model use?

Accepted Answer

The model uses ~160 features including ELO ratings, rolling form, venue stats, weather, referee bias, positional lineup strength, and market odds. Alphr's NRL XGBoost models are built on approximately 160 engineered features per match. Key feature groups include: team ELO rating difference, rolling 5- and 10-game form metrics (wins, scores, margins), venue-specific home advantage, weather conditions, referee-specific penalty and scoring tendencies, positional player ELO aggregations (forwards, halves, backs, hooker, middle), head-to-head history, rest days, and Sportsbet market odds. All features use anti-leakage window functions — only past data is used, never future information.

Question 9

Does Alphr's NRL model account for referee bias?

Accepted Answer

Yes — Alphr's NRL model includes referee-specific features tracking historical penalty rates, scoring patterns, and home advantage tendencies per referee. Referee bias modelling is a distinctive feature of Alphr's NRL system. The model tracks each referee's historical tendencies including: average penalties per match, home vs away penalty splits, average total score in matches they officiate, and how those stats deviate from the league mean. These features help the model capture systematic refereeing patterns that affect match outcomes — for example, some referees consistently produce higher-scoring games or stronger home-field advantages.
