I'm fairly new at this and had question about anodizing multiple pieces. How important is it that every thing in the run is close to the same size(surface area)?

I made a run today with three pieces that were 16, 46 and 69 sq in. (131 total). I ran at 6 a/sf (5.5 amps) for 108 minutes shooting for 0.9 thickness. It appears that the smallest piece turned out the best (It seemed to take the black dye better).

Thanks for your help.
