  This paper deals with an improved version of the deck of the cards method to
render the construction of the ratio and interval scales more `accurate'. The
improvement comes from the fact that we can account for a richer and finer
preference information provided by the decision-makers, which permits a more
accurate modelling of the strength of preference between two consecutive levels
of a scale. Instead of considering only the number of blank cards between
consecutive positions in the ranking of objects such as criteria and scale
levels, we consider also the number of blank cards between non consecutive
positions in the ranking. This information is collected in a pairwise
comparison table that it is not necessarily built with precise values. We can
consider also missing information and imprecise information provided in the
form of ranges. Since the information provided by the decision-makers is not
necessarily consistent, we propose also some procedures to help the
decision-maker to make consistent his evaluations in a co-constructive way
interacting with an analyst and reflecting and revising her/his judgments. The
method is illustrated through and example in which, generalizing the SWING
method, interacting criteria are aggregated through the Choquet integral.
