The source says percent, not one proof point. It does not specify relative percent versus percentage points or provide paired measurements; do not convert this into a numeric proof trajectory. Humidity is not isolated experimentally.
The profile contrasts Gulf Coast conditions with more familiar hot-climate Texas maturation accounts.
In Martini's Gulf Coast profile, Julian Giraldo says that in some cases proof rises only 'one percent' during sea-level maturation, and describes trials with different entry proofs.

Context and interpretation
The passage is attributed producer testimony showing why Texas subregions cannot share one assumed maturation trajectory. It does not isolate humidity, heat, airflow, warehouse, barrel, or inventory effects.
