One then enters the number from the
scale that is appropriate for the judgement: for example enter 9 in the (coffee, wine)
position meaning that coffee consumption is 9 times wine consumption. It is automatic
that 1/9 is what one needs to use in the (wine, coffee) position. Note that water is
consumed more than coffee, so one enters 2 in the (water, coffee) position, and ½ in the
(coffee, water) position. One always enters the whole number in its appropriate position
and automatically enters its reciprocal in the transpose position.
