Model insights
- 01 The least accurate Gemini and the most reluctant to leave "low" — it reaches for "medium" far less often than its own flash siblings and pays for it with twenty-five downward misses.
- 02 Two three-day July streaks show it holding "low" through sustained bad weather, at eight times the flash-lite price.
