I'm not sure where those instructions came from. They are not in my owners manual. However, I can achieve those measurements without even connecting the spring bars as the airbags will automatically adjust the suspension to re-level the TV body. The airbags do nothing to actually transfer load to the front axle.
Additionally, if you shut the engine off (to disable the airbags) then raise the trailer tongue connection to install the spring bars, the auto level system will dump air out of the bags (since you raised the rear of the TV). That dumping of the air will make your measurements invalid since the ride height of the suspension system is changed since the original measurement.
That's why I was trying to do the set-up using weight since the ride height varies due to influences other than tongue weight and spring bar tension. Hope that makes sense.
