Yes, the rest of the information

Yes, that may mean some extra work.
Collecting Range type information
that is going to be used in the
election may be even more difficult
(because of strategic interest not
to give sincere opinions).

CWP could collect sincere ratings
data even in competitive environments.
One more observation. If we want to
collect sincere non-normalized
ratings data it would make sense to
define some reference points.
For example in range [0,1000]:
900 = best possible candidate
800 = excellent candidate
700 = good candidate
500 = average candidate
300 = bad candidate
200 = terrible candidate
100 = worst possible candidate
