Model insights
- 01 The family's expensive disappointment: the priciest Gemini yet 13+ points behind its flash-lite sibling.
- 02 It is stuck near "low" (124 of 155 days) and "optimistic" (29 under vs 2 over), including an 11-day run of "low"-vs-"medium" misses across July — the drift is ongoing, not historical.
