If I understood properly, one of the overhead rigging lines for the floating anchor (or both for some amount of time, before being reset) was natural crotch rigged. How much, if any, damage occurred to that crotch on the indestructable tree from the anchor rope sawing back and forth with that dynamic loading?
I can see signs of a rope going back and forth over a natural crotch from ascending on SRT, and that's minorly dynamic loading with a much smaller impact force.
Did you set the ropes through the natural crotch with some type of tube style cambium saver?
Will cambium damage mean more work in the future?
How did you access the anchor rope to reset it? Were the oaks indestructible enough to withstand being spiked to reset the rope? Not a charge, just an open-ended question. I haven't seen you doing any spikeless climbing, so I'll ask.
