Do weights need to add to 100%?

Not necessarily. This tool normalizes the weights automatically, but showing percentages that total 100% usually makes results easier to interpret.

Can weights be zero?

Yes. A zero-weight item is ignored in the final weighted result.

Does this run locally?

Yes. All calculations stay in your browser.
