How much did the sum of your TV front axle, rear axle and trailer axle change? that is how much the tongue weight changed. I bet the sum of the weights didn't change by more than 50lbs.
The WD hitch moved weight from the TV rear axle to the trailer and TV front axles.
The total of all axles (truck and trailer) doesn't tell us anything about tongue weight.
The tongue weight is the weight of the trailer minus the weight on the trailer axles.
Alternatively, you can also do it by comparing the truck axle weights by themselves vs the truck axle weights with the trailer attached. The difference is tongue weight.
With the WDH attached, more weight is on the trailer. On mine, the CAT scales said it was around 200lb less with the WDH connected vs just the ball by itself (bars were placed on the A-frame so the weight of the bars didn't impact the results).
