Read the explanation
This explanation examines the calculator critically rather than recommending campaign messaging or targeting. At default inputs forty five, seventy and sixty, the source directly assigns score seventy eight for its selected fixture. Generic arithmetic with the same profile would be eighty two minus the ten point focus difference times point two five minus the five point risk difference times point three plus point eight five times four. That yields eighty one point four, rounded eighty one. Bars compare seventy eight and eighty one at two pixels per rubric point. Neither number comes from a voter survey, experiment, trained predictive model or electoral observation. A source interview reference does not validate the score or its messaging suggestions. For an arithmetic audit, changing only the risk control to one hundred with the same focus inputs gives eighty two minus two point five minus eighteen plus three point four, or sixty four point nine, rounded sixty five. Bars compare the arbitrary reference sixty and the sixty five result at three pixels per score. The page converts score to a net voter shift by subtracting sixty and multiplying by point two two. Sixty five becomes one point one percent while fixed seventy eight becomes three point nine six, displayed four percent. These shifts are algebraic captions with no empirical causal basis, election outcome or uncertainty calculation. They should not be interpreted as evidence that changing a position persuades any demographic. The canvas marker radius is eight plus the risk slider fraction times sixteen. Default forty five gives fifteen point two graphics units and one hundred gives twenty four, drawn at six pixels per radius unit. The position independently maps two focus percentages into fixed canvas coordinates. This is a visual encoding of controls rather than measured electorate behavior. Demographic profiles attach authored weights and descriptions; the code does not establish that those groups hold the stated preferences, and confidence wording is not a statistical confidence interval.
