There is one answer, so nobody has to pick which to believe
The rules live in one place, and the desk, the phone in the cab and the dispatch system you already run all read from that same place.
Why this is different
Most yards run a spreadsheet on the desk and a rule of thumb in the cab. The two agree until a load is close to a limit, which is exactly the moment they stop agreeing.
The spreadsheet is working from a 34,000 lb drive tandem. The driver has run a 30,000 lb rule of thumb since a citation years ago. The load sits on the dock until somebody senior picks a side, and whoever picks is guessing. When both are reading the same record there is nothing left to pick.
