Brazil’s Serie A resumed for Matchweek 4 with a mixture of tight draws, narrow away wins, and a standout Flamengo victory that saw the model's forecasts come within a whisker of perfection. The only stumble was a medium-confidence total-goals call, but the night otherwise belonged to the analytical engine, which nailed everything from the exact scoreline to the half-time/full-time outcome as Flamengo dispatched Mirassol 2-0.
How our forecasts did
Only one fixture carried published calls in this round, yet the scoreboard was busy. All seven forecasts from that single match were graded, and six landed correctly.
The sole blemish came in the total goals market, where our medium-confidence call for more than 2.5 strikes fell short as Flamengo and Mirassol managed only two between them. Every other topic hit its mark: match result, win or draw, both teams to score, first team to score, exact scoreline and half-time and full-time all recorded a perfect one-from-one record. The exact scoreline and half-time/full-time predictions were both longer shots, making their success particularly noteworthy.

Tuesday, 2 September
Flamengo 2-0 Mirassol
The standout fixture of the round — and the only one backed by the model — saw Flamengo cruise to a 2-0 home win over Mirassol. All four result-oriented forecasts came off: a Flamengo win, Flamengo to win or draw, Flamengo scoring first, and the exact scoreline of 2-0. The both-teams-to-score call — at least one side would blank — also landed. Only the over 2.5 goals forecast missed, the two strikes falling one short of the target. Flamengo’s defensive resilience at home held firm, while Mirassol’s recent scoring habit ran aground against a well-drilled back line.
What we got wrong
The night’s only incorrect call was the medium-confidence expectation of more than 2.5 goals in Flamengo’s meeting with Mirassol. The model’s reasoning, noted in the pre-match analysis, highlighted a tension: Flamengo’s home defence had kept six clean sheets in eleven outings, yet Mirassol had scored in nine of their previous ten matches overall and were prone to conceding late. In the event, Flamengo’s clean sheet held and the contest produced exactly two goals — the first coming from the hosts, and the second sealing the result without ever threatening to crack the over line. It was a case where the visitors’ attacking numbers promised more than they could deliver on the night against a stingy home side.
What the round changed
Flamengo’s victory extended their winning sequence and underlined their title credentials early in the campaign, while Mirassol’s away-day problems persisted. Elsewhere, the spate of 2-1 scorelines and draws kept several mid-table races tight, with little separation emerging. The model’s single-fixture forecast set delivered a strong performance, missing only one call on a night where the football largely followed the script — except when it came to the number of goals.
