How the chart is checked
A refresh fails closed. When the file cannot be read, or two readings disagree, the period is blocked and no rate is filled in.
Nothing in this note is estimated. When a displayed figure disagrees with the official publication, the publication wins. That rule is recorded under corrections.
Rate monitoring is not a tax calculation
This note reports how the Wisconsin publication is monitored. It does not calculate tax on a cart, invoice, ZIP code, or address, and it does not file a return.
