A 19-2 strawweight whose composite rating of 7.8 is built from exactly one recorded fight, against an opponent who has not won two in a row in her recorded five.
Xiong Jingnan's composite rating is 7.8 and every one of her style scores — striking, grappling, wrestling, submission, pressure, volume — reads 0.0. Her performance average is 0.0 and her quality-of-victory is 0.0. None of that means what it appears to mean. She has exactly one recorded fight in this database, a decision loss to Angela Hill in May 2026, and a single loss is not enough for the mod…
Xiong (19-2) has one recorded fight in the database — a decision loss to Angela Hill in May 2026 — which is why her composite reads 7.8 and every style score reads 0.0. Her height and reach are not on file. At 38 she is the elder by ten years, and her 98.0 chin rating is the only metric here that a single fight can support.
Polastri (14-6) has lost three of her recorded five, most recently a decision to Talita Alencar in April 2026, but knocked out Karolina Kowalkiewicz in the third round in October 2025. A 47.7 composite, a 94.0 chin rating and a 0.5 finish rate across five recorded UFC appearances. At 28 she is the younger woman by ten years.
Xiong's 7.8 composite and all-zero style scores come from one recorded fight — they measure nothing
A 19-2 record against a fighter who has not won two in a row in her recorded five
Polastri's 5.8 striking and 0.5 finish rate against a 98.0 chin rating
Xiong's height and reach are not on file, so even the physical matchup is guesswork
A ten-year age gap, 38 to 28
Xiong has one recorded fight; if her 19-2 record reflects her actual level, the ratings gap is meaningless
Polastri has lost three of her recorded five and beats good opponents only intermittently
Two chin ratings above 94.0 make an early finish unlikely in either direction, which favours whoever is better over fifteen minutes — and that is genuinely unknown
