Actually, not flow charts as such, but rather questionaires which compare one’s own position to, say, 30 official party positions for a number of parties exist on the web in Germany. They can be quite enlightening (such as when well known politicians take the test and find that their positions most closely match those of a party which is not their own) as far as getting an overview of the positions, but of course don’t answer the question to what extent the party in question, if elected, would actually implement all the stated goals. In practice, there are coalition governments, and which party gets which positions (when the coalition parties are in disagreement) is of course subject to their own weighting and negotiation skills.

Of course, his point is that our “knowledge” can change with time. However, his comments on the chart have been up for several years now, and the numbers have hardly changed—certainly they haven’t move out of realistic error bars—which gives some indication that we really do have an idea what these three numbers are.
