To be fair (though I wish you'd just appeal with this argument rather than try to make a conflicting precedent which I'd appeal as being inconsistent with the old one), this is the point that gave me the most back-and-forth in my own mind. I thought about allowing it only if the historical series a particular VVLOPs contained enough minus operations. But aside from the recordkeeping headache, in the end I felt that even starting with a default value of 4 could be the sum of an arbitrary number of +1s and -1s, for example (10,000 +1, 9,996 -1). The real solution is to actually define "parameter" in the rules. :) -Goethe
