What do these words mean?
Right
It turned out the way this report said.
Partly right
Some of this was right and some of it was not.
Wrong
It did not turn out this way.
Moving target
This was right about the plan at the time. The company then changed it.
Never settled
The company has announced the product and nobody ever confirmed or denied this.
Not comparable
This measured a different thing from the number the company published, so the two cannot be compared.
No outcome yet
Nothing has happened yet that would prove this right or wrong.
Not checked yet
The company has answered this. We have not finished checking this one.
Checked
Checked means the company has since given an answer and we compared it with what was reported. Details still waiting on an answer, details nothing can settle, details where the plan itself changed, and details we have not finished reviewing are all counted separately and are not part of that number.
Moving target
A moving target is a report that described the plan accurately at the time, on a product the company then changed. We count these on their own: it would flatter a reporter to call them right, and it would blame a reporter for a decision that was not theirs to call them wrong.
