Are you using raw scans from Vuescan (i.e. Output tab -> Raw file |X|, and "Raw file name" specified) for scanning both, the target and your slides - bypassing any color corrections in Vuescan?
Yes.
Do you use the same exposure value for scanning the target and your slides?
Probably not. I was letting the scanner determine exposure, which might be different from slide to slide. I didn't confirm that it was the same. This is probably the problem, no? I will try again this evening.
Are your slides the same film brand as the target? (i.e. is it granted that Dmin of your film material is >= Dmin of the target?)
Yes, in this case all Kodak Kodachrome.
