I think that's too flexible. Allowing a single voter to give multiple
votes (but at fractional power) can be justified by that the voter is
judging the candidates on seperate metrics. The sum matrix is still a
proper tournament matrix. However, letting the voter arrange his
contribution to the Condorcet matrix as he wishes may let him move the
matrix out of what could be reached by ordinary votes, which seems
nonsensical.
If one desires such flexibility, it should at least be phrased in terms
of contests. That is, setting M(A,B) to q means you prefer A to B by
fraction q, or that A won in a "match" of some sort when facing B (such
as with round-robin tournament matrices in sports).
