We are currently doing some studies on our copper baths. Recently I have been given some conflicting information/guidelines regarding cathode to anode surface area ratios and distances. Could someone please provide me with their preferences/experience to the following questions.

Q1. When calculating anode area, is only the surface facing the panels to the calculated or 
       do you calculate the entire circumference?

Q2.  How much anode area should you have facing the panel surface area. The most recent 
       information I have been given indicates you should have at least an equal or 1/1 ration. 
       This would result in having at least  7- 21/2" anodes on each 42" bar or 3 anodes facing 
       each panel with one anode in the middle. 

Q3.  I have been told by some suppliers that you never want your anodes shorter than your 
       panels yet I have recently been advised that my anodes should be about 2 inches 
       shorter than my panels. I'm interested in getting feed back on this matter.

All responses will be appreciated.
