Silvio Duran and Thiago Macedo met 6 times on record, all in the gi and all inside IBJJF Open brackets. Macedo holds the edge at 4 wins to 2. Five of the six meetings landed in a final, and their earliest recorded clash came at the 2017 IBJJF Cincinnati Open. These were peers fighting for the same featherweight podiums, not a one-sided series.

None of the six ended by submission. Macedo took three of his wins on advantages, one on points. Duran's two wins came by decision and by points. That fits the broader numbers: neither man is chasing the finish against the other, and both lean on positional scoring. Duran's recorded submission rate on his wins is 30% against Macedo's 14%, but in this rivalry the tap never showed up.

Stylistically the split shows in their finishing tools. Duran's most frequent recorded finish is the Straight Ankle Lock with 11 wins, a leg-attack signature. Macedo's is the Armbar with 7 wins. Against each other, though, the matches were decided on the scoreboard rather than by either man's preferred submission.
