A usage number without a timestamp is a guess
“You have 86 GB left” — as of when? Why every usage figure should say how old it is.

Proxy usage is measured by the network that carries your traffic, then reported to whoever sold it to you, then shown on a dashboard. Each hop adds delay. A dashboard that hides that delay is showing you a number that may already be wrong.
Three things a usage figure should carry
- When it was measured by the network
- When it was last synced to the dashboard
- Whether that is recent enough to trust
With those, “86 GB remaining” becomes a decision you can make: top up now, or wait for the next sync. Without them, it is a hope.
Counters go backwards. Usage shouldn’t.
Usage counters reset, arrive late or arrive twice. A careful system treats each reading as evidence, never lets total usage decrease because of a glitch, and flags the reading for a person when something doesn’t add up.
