Common tally mistakes
The recurring errors that decide petitions, from more votes than voters to duplicate serials and bad arithmetic, and how to catch each one.
Most disputed results do not turn on dramatic fraud. They turn on ordinary mistakes, the kind that creep into any process where thousands of forms are filled by hand, at speed, late at night. The good news is that the common ones are well known, and every one of them can be caught. Here they are.
More votes than registered voters
A station cannot record more votes cast than it had registered voters. When it does, something is wrong: a miscount, a transposed figure, or a form filled in error. It is the easiest check to run and one of the most revealing. Every station's total should sit at or below its registration.
A form serial that appears twice
Each results form carries an official serial number, and each belongs to exactly one station. If the same serial turns up for two different stations, one of them is wrong, through a plain error or a form where it does not belong. A watch for duplicate serials catches a class of problem that raw vote numbers never will.
Arithmetic that does not add up
The numbers on a single form have to agree with each other. The candidate votes plus the rejected ballots should equal the total ballots cast, and that total should match the turnout. When the arithmetic inside a form does not close, the form is unreliable, no matter how confident the figures look.
Transposition and typing errors
A 1,204 recorded as 1,240. Two candidates' totals swapped. A digit dropped. These are honest slips, but they move numbers, and at scale they add up. When you capture the photograph of the form and not only the typed figure, you can catch and correct them against the source.
Turnout that does not fit its neighbours
A single station that reports turnout far out of line with every station around it is not proof of anything. It is a question worth asking. Outliers are where you look first, because that is where both errors and problems tend to show.
Missing forms
The quietest mistake is the one you never see: a station that never reports. A blind spot is not a zero. It is an unknown, and unknowns are where a result can be decided without you noticing. Coverage tracking turns "we did not hear from them" from an accident into a flag.
Catching them is a system, not a squint
No one catches these by staring at a spreadsheet at 2 a.m. You catch them by running the checks automatically, as each form is captured, so the exceptions come to you instead of hiding in the pile. That is the whole point of a command centre.
Election Edge runs these checks on every submission as it arrives: votes against registration, duplicate serials, form arithmetic, turnout outliers, and coverage gaps. Each flag links back to the photographed form. The mistakes are common. Missing them does not have to be.
