I may be able to try that today. My cathode area is pretty large (at about 7 square feet) each compared to the batch size.
The 2011 voltage curve falls off a lot more in our setup when compared to 6011.
One thing I have done to expedite calculating "optimum" anodize times is to load up a rack of parts, and pull one off every 5 minutes or so (and adjust the current accordingly). Then they can be layed out and compared after they are dyed and sealed. It graphically illustrates the difference, the first ones take longer to dye and don't reach the color depth, then they dye progressively faster and deeper, and one anodized beyond that for long enough you can see the effects of too much anodize time.
