Where the next machine goes
The fund can afford one machine at a time. Picking by gut means picking whoever asked loudest, so this ranks stations by value created per dollar landed, using real weather.

The weather it's reading
Real daily observations from Open-Meteo's archive at each station's coordinates. Arabica flowers when rain breaks a dry spell, and ripe cherry follows roughly eight months later, so the crop a station delivers in March was decided last September.

The model
Flowering rainfall Rain after a dry spell sets the flowers that become next season’s cherry. | 250–450 mm weight 0.34 |
Dry spell before flowering Without a dry period arabica flowers out of sync and the harvest straggles. | 14+ consecutive days weight 0.22 |
Bean-filling rainfall Water stress while the bean fills shrinks the cherry and the screen size. | 200–400 mm weight 0.26 |
Heat-stress days above 30 °C Arabica photosynthesis falls off above about 28 °C; sustained heat aborts cherry. | 0–5 days weight 0.18 |
| Baseline, mature tree | 2.00 kg cherry |
This is a transparent model with published coefficients calibrated from arabica literature, not a trained model, because ground truth for these stations doesn't exist yet. The weather is real; the weights are a prior.
What makes that honest rather than hand-waving: the platform is already collecting the training set. Every kilo logged through the station phone is one labelled example against a forecast that was made months earlier. After three seasons this page shows a fitted regression and a backtest error instead of a table of priors.
