Healthy zigbee mesh?

So after adding 4 more repeaters (plus 5 additional leak sensors) and resetting every battery device, this is what my mesh looks like, after about 72 hours. So far no drops and all leak sensors been reporting on state change as they should (been testing everyday), so hoping i finally got my zigbee mesh where it needs to be.
This is what it looks like, after leaving the graph running for 24 hours. Does this look like a healthy mesh? Is with zigbee, its the same as with zwave, where more multiple routes you have the better?
