A growing number of election integrity advocates and activists are drawn inexorably to the conclusion the best system available is paper ballots marked by the elector and counted by hand. This system is transparent, understandable, reliable, and provides for recounting in the event of an election dispute. The single greatest objection presented by vendors of election machinery is that hand counting thousands of ballots would be prohibitively time consuming and prohibitively expensive. Neither claim withstands scrutiny. This paper describes how to efficiently count ballots by hand with the aid of a good counting scale.
During the late 1970’s and early 1980’s a new technology, the counting scale, was introduced to inventory control systems and warehouses around the world. A counting scale is a sensitive scale with a microprocessor and enough programming to convert an arbitrary weight from the scale sensor into a piece count on the front display. The scale used at your local grocery store to calculate the cost of your produce or meat is a kind of counting scale which calculates dollars instead of piece counts. To count the number of nuts or bolts in a display bin, hardware stores routinely use a counting scale. The scale is programmed by carefully counting out a sample of the bolts to be counted; e.g. 10 bolts. The more bolts in the hand-counted sample the more accurately the scale can convert weights into piece counts. The scale is then told how many bolts are on the scale weighing plate. From the weight and number entered, the scale can calculate the weight of a single piece. For example if the scale detects 2.15 pounds and the user enters 10 as the piece count, the scale internally calculates the figure of 0.215 pounds per bolt. Once this initial programming is done, the scale will correctly read 123.20 pounds as 573 bolts and 175.655 pounds as 817 bolts. Of course any material on the scale which weights 123.20 pounds will be interpreted by the scale to be 573 bolts. The programming on of the scale is very simple, direct and robust.
For the example election in this paper the author has selected the November 2, 2004 election in the Village of Brown Deer, Wisconsin. This election and polling location was selected because it had the most number of ballots of any polling place in the State of Wisconsin for the November 2, 2004 Presidential election. There were 7080 ballots cast in the Village of Brown Deer and the ballot contained 10 partisan elections. This is the most extreme reporting location for any of the last 5 elections in Wisconsin. The naïve approach to counting these 7080 ballots by hand is to examine each ballot in turn and transfer the votes recorded on the ballot to a tally sheet for each of the 10 elections. This method requires about 1 minute per ballot. For the Village of Brown Deer this would be 7000 man-minutes of counting or 117 man-hours. With 34 people the ballots could be counted in 3 hours and 45 minutes. This approach clearly is unfeasible for a count effort of the size of Brown Deer.
Here is a more efficient approach.
i. 5 people each count out 5 blank ballots,
ii. Collect the 25 ballots into a stack of 25.
iii. Repeat 10 times. This will produce 10 stacks of 25 ballots each
iv. No each of the 5 people takes 2 stacks and verifies each contains exactly 25 ballots.
v. Viola 250 ballots counted. For testing sake lay the stakes crosswise so groups of 25 are can easily and accurately be removed from the scale as part of step d.
i. Remove and re-add various groups of 25 ballots to and from scale. Verify each time the number displayed by the scale is the correct ballot count.
ii. Add and remove single ballots, pairs of ballots and groups of 5 ballots. Verify each time the number displayed by the scale is the correct ballot count.
The use of the counting scale divides the work between humans and computers along the strengths of each. People are very good at sorting items and pattern recognition. The computer is good at measuring weight and calculating the number of ballots from the weight.
With the procedure above, how much time and money will be spent on election night counting the ballots? Here is a breakdown of the costs and time involved:

A good counting scale for counting ballots would need to be a high capacity and high sensitivity scale. Capacity is the number of pounds of material can be weight at 1 time. Sensitivity is smallest weight which the scale can distinguish. Such a counting scale from Mettler-Toledo, Rice Lake Weighing Systems, Sterling Scale Company, or Fairbanks Scales will cost approximately $1600 to purchase and require an annual calibration for about $300 dollars.
See: the Rice Lake Weighing Systems quote: http://www.washburnresearch.org/archive/HandCountingBallots/DIGI_DC-200300.pdf for a Digi by RLWS
See: the Mettler-Toledo quote: http://www.washburnresearch.org/archive/HandCountingBallots/MettlerToledo_jmm20050805_1.pdf for an MT Series 4 counting scale.
This money will buy a counting scale with a capacity of 50 to 70 pounds and a sensitivity of 0.005 pounds (2 grams). A single 8.5”x11” sheet of 80 pound card-stock weighs 8 grams. A ballot printed on heavier card stock or on a larger size would weigh more. Thus the ballot is well above the readability of the scale and is able to distinguish differences of even a single ballot.
The programming required for each election is 1 hour of time and is included in the $1000 dollars cited above. Also since counting scales are designed for use in an industrial setting and for continual use, a good counting scale should prove more durable than most electronic voting systems.
Hand counting paper ballots with the aid of an excellent counting scale is a voting system which has:
1. Lower equipment acquisition costs,
2. Lower equipment maintenance costs
3. Lower election administration costs per election
