Here is the part that matters for going unbeaten: the simulation does not roll the five sub-stats separately. It starts with the average overall of everyone you drafted, adds up to 12 strength points for chemistry, then rewards depth and penalises weak links or badly unbalanced units. That final strength sets a sport-specific per-game win probability.
Because the model sees the average and its weakest parts, one 99-rated superstar surrounded by weak picks loses to a balanced squad of high-80s team-mates who all link together. Drafting whole blocks from the same team and season is usually worth more than chasing a single big number. The full mechanics of links, eras and nations are in our chemistry guide.
For how that maths translates into a perfect Premier League season (re-roll timing, which positions to gamble on, and how the tier ladder works), read the guide to going 38-0, or browse the rest of the guides hub. And if you arrived here from 38-0-0.com or 82-0.com, note that everything on this page describes Go Unbeaten's own engine. We are an independent fan project, not affiliated with either site or with any league or governing body.
These are the casual-play clamps in the current engine. World Cup mode adds tournament pressure and caps a single match at 80%. Daily challenges may apply their published qualitative theme through a separate deterministic modifier.
