Fibergeek, one of the things I have learned is you are right and that the connection is important. I haven't got a lot of experience, but for the last 6 weeks have been anodizing parts every day almost. When I first got a "real" power supply, I was seeing peak voltages of 13-15 at 4.5 amps per square foot. The area calculations of individual parts are from a CAD program where the parts are modeled in 3D, so that part of the equation is likely pretty good. I thought the connections were good, and questioned your figures and power supply meter accuracy. I was using wires with aligator clips to make the connection to the hanging wire (away from the sollution). When I changed that, the voltage dropped. Then I realized the aligator clips were not making as good of a connection as I had believed.
Even though it is somewhat related to color depth, I'll start a new post about the dye, I believe I can share some expeience and insights I have learned that may help those having problems.
