Tipping & predictions

A transparent Elo rating, built only from this season's 1st-grade results — no betting odds, no external data. It would have called 68% of results right so far (53 decided matches).

Elo is the rating system used in chess and by FiveThirtyEight. Every club starts level on 1500, then trades points after every game based on who won, the margin, and home-ground advantage — beat a stronger side and you gain more; lose to a weaker one and you drop further. A higher number means a stronger club right now — often ahead of where the ladder has caught up.
