Zigbee Child Data Table Question

I'm always fascinated to see some of the routing choices my devices make. I know that some of it is just orientation of the antenna with the antenna of one repeater versus another. But some always shock me. And I'm not talking new devices either...I'm talking devices that have been around for a while.

I can also report that 4 days after removing my Peanut plug, I no longer see bunching in my network where a couple repeaters were not used at all. For the longest time I had two repeaters that had zero devices connected to them. 4 days after pulling my peanut plug, i have a complete even distribution of devices across all the repeaters now. And things are working much faster. Is that just coincidence or do the peanuts have something to do with it? Well, the only way to know for use would be to add them back in but I've got enough evidence for me to conclude that they were the culprit. Anyways, they will no longer be on my recommended device list.
