You need two passes at the scale to determine tongue weight and a third to determine how well the WDH is adjusted.
Truck with trailer without WD bars sum of axle weight minus truck alone sum of axle weight equals trailer tongue weight.
If you did not use WD bars for example, you TW would be (3300+3820)-(3600+2600) or 940 pounds. IF your WD bars were doing anything then tongue weight will be higher ans some TW is transferred to the trailer axles.
Without the third pass, it is hard to judge TW and how well the WD is adjusted. However, all your weights are under the truck's ratings. You may want a little more WD force which can be accomplished with more hitch head angle or fewer links under tension. Ford recommends only restoring 50% of front axle weight lost due to trailer tongue weight. You lost 300 pounds with WD. 600 pounds lost would be higher than I expect with your TT weight. I have seen this for pickups and RVs with about 1000 pounds of TW.
TT drop tongue on ball:
truck front axle -400 pounds
truck rear axle +1400 pounds
TT with WD:
truck front axle same as unloaded
truck rear axle +800 pounds
TT axles +200 pounds
