Band 8.5 means performance sits between Band 8 wide control and Band 9 near-native ease: slips are very rare and never systematic. Examiners see sustained precision in task focus, cohesion, and lexico-grammar across the whole test. Listening/Reading at 8.5 is ~37/40. The gap to 9 is not more hours. It is eliminating patterned micro-errors under exam fatigue.
