This doesn't make it wrong. It just makes the margin of error a little higher. The main point there was that position does affect how salary is calculated, and the work done offers a pretty conclusive proof.
Most importantly it has nothing to do with how cap works.
Of course it doesn't. This was an answer to the question someone asked about whether the best position affects the way salaries are calculated.
