Looks to me like you have:
trailer weight = 9260
tongue weight = 1140
without WD you had made the front of the truck light by =
480
...and with WD you had restored =
300 of that 480 and further, the WD had moved =
170 more to the trailer axles.
If it were mine, I would try to get more weight to the front axle of the truck. Although that may not happen depending on what WD hitch you are using. Some will argue that you do not have restore 100% of the front axle weight, and that is in fact true for some of the late model trucks. I stated that I would try to get the front closer to it's original weight, and will admit I am stating "that is my preference".
So hopefully, that stop any of the arguments about whether 50% restoring is correct, or closer to 100% is correct. Your arguments may vary....
EDIT: so you say the wife was not in there at all during any of the passes ? If that is the case, your trailer weighs 9260
EDIT to correct some of my math
