I am a little curious.. how often do you rotate your eggs Volleyball Style? Because, I'm thinking that an egg which starts at lower left, marches along the sidewall to the LR corner, then jumps to UL, then marches along the other wall.. that's 12 steps before it can begin to move away from the walls..
I love the plan, I think it's brilliant.. but I'm wondering if there might be an advantage to imagining that volleyball net across the middle and rotating them as two teams, or even imagining 4 quadrants and rotating each group within its quadrant (in the LR quad, the LR (server) egg would rotate to its quad's UL position, which would be (Excel spreadsheet reference) cell D5 of the whole box. Whether two or four teams, the 4th row (directly under the imaginary net..) would be different.. there, the eggs would step through A4 to B4 to C4 to A4... or F4 to D4 to E4 to F4.
If you're rotating places 4 times a day, your plan cycles each egg through the whole box two times.. but that seems like a lot of opening the box and handling the eggs. By rotating within quadrants, one place rotation per day moves each egg through its quad 2-1/3 times.
Your way is probably just fine.. I'm sure that many folks use that incubator without doing any place rotation at all, and have good hatches.. I'm just OCD enough that I'd have to rotate in quadrants...
