Almost 10,000 miles in a 3.5 eccobost on Edge 0W40, and 7k miles was towing.
The oil did fine. You can see it's a Euro oil with the high zinc (973 ppm) and good retained TBN (3.17), plus you have the Castrol Edge Titanium dose at 45ppm plus a touch of Boron at 28 ppm. A nice oil.
The iron wear is 30 ppm which is fine. The KV100 viscosity is 12.6 cSt which still seems OK to me, especially given many people would use an ILSAC 30 grade with a fresh KV100 of 10 to 11 cSt.
I can't help but to compare this to quite a few EB UOA's I've seen recently running Castrol Magnatec 5W30 (ILSAC brew). The Magnatec tends to show a bit less wear metal in the iron (about half), but there is nothing wrong with your iron numbers and you did push your EB much harder than most, so no problem. Your Edge, being a euro oil has higher zinc and ample TBN at 10k miles, while the Magnatec show less zinc and the Magnatec TBN looks spent to me after 9k miles.
At 10k mile OCI with heavy towing, I would stick to the Edge.
