I don't really see any problems. You created the soundcard.cal file that appears to create a flat line on the loopback cable when measured.

I wouldn't worry too much about anything below 10Hz - you won't be measuring there.

Thanks brucek. I was concerned about the first soundcard reading where there is nothing under 30Hz. Doesn't that mean that my soundcard isn't picking up anything below that level? In other words, how am I going to get accurate s/w measurements? Or is that what the .cal file does?
