This could be the case, however, it could also possibly be the fact that they only tested a relatively small sample (450), and they could have shown that they have improved. However, if a much larger sample was done, say 4500, then it would be more likely to give an accurate figure. However, there is always the possibility that this could have been improved due to the improvement in employee training
