The arithmetic, made visible.
days × people × [(video hours × video GB/hour) + (audio hours × audio GB/hour) + browsing GB/day + other GB/day] × (1 + buffer/100)
The starting assumptions are 1.2 GB/hour of video calls, 0.08 GB/hour of audio calls, 0.25 GB/day of browsing and messages, and 0.5 GB/day of uploads or other use. These are editable planning examples, not field measurements. Count shared usage once; downloads and system updates belong in other use.
