Coverage across the operators we sampled in the past seven days is 96.4%: when we visit an operator page, we produce a usable welcome-offer record almost every time. That is the number we hold ourselves to and the number we suggest you quote.
A small share of operators in smaller markets are not on a daily cadence yet — long-tail brands where the value of a fresh snapshot every 24 hours is lower than the cost of one. Those are clearly marked in the per-operator history and the dashboard never silently presents stale data as fresh.
Continuous per-operator history is the spine of the product: every welcome-offer field is timestamped, every change is traceable, and nothing is overwritten in place. Older context is available on request for select markets where we hold deeper archives.
