  ],
  "reviewNote": "Reviewed after the latest Festival Hall and colonnade work. The overall estimate remains about 25%: one area has gained considerable detail, but most of the fair still needs much closer reconstruction. More source records and more model detail do not, by themselves, justify a larger whole-fair percentage.",
