Hmm I could evolve the qc0 example in McLachlan. Maybe there are
differences in the parameter file that make the error "obvious".

Are you maybe looking at the z=0 plane? That plane has a weight of 1/2
since only half of the volume of each cell is used when eg. computing
the simulation volume. I have never used CarpetMask myself (but have
written a similar thorn of my own... would have paid to look into Carpet
first I guess :-) )
