In my opinion, wait times for voters of more than 30 minutes should be grounds for civil suit or impeachment of the election officials responsible. Other variables of interest would include voter dwell time - the time it takes for one voter to cast their ballot - and the likelihood of machine malfunction, whether from inadequate preparation or maintenance, or from active sabotage by voters. Worst case is a polling place with minimal staff, fragile and antiquated machines, and a high proportion of impatient, frustrated, or angry voters. The procedure for repair of machines (never use the word "fixed" during an election) is to mark the machine as out of order, call the elections office, and begin a long wait. For non-Americans, note that US general elections typically involve 2 or 3 dozen contests, so marking paper ballots just for one party or another is not an effective option in the US.
