Maybe your scoring device is better than bridgemates. I believe you. All I am giving is my experience.
We use BridgeTab, an Android app that runs on tablets, rather than BridgeMate. Theoretically, it should be much harder to get the declarer wrong, as you're tapping on a seat in a table diagram. Yet hardly a week goes by that someone doesn't enter the direction wrong. When the opponent verifies, they often just look at the contract and result, they don't always check the direction, so this gets by.
This happens most often when we use robots to fill in a half table in the movement. The robots get the stationary north-south position in the movement, and the humans sitting east-west have to enter the result in the tablet. Since we're so used to only entering scores when we're sitting North, it's easy to get the relative direction wrong. Last week there were 3 scores entered wrong at the robot table.
Face it, we're all human and we make mistakes. Verification can reduce them, but it won't get rid of them entirely.
