I have two thoughts.
One, as my colleague Mr. Ngan indicated, the lag in collecting the data, doing the modelling and providing the analysis can take up to 18 months. The ability to determine whether the interim objective has been met would depend on the timing of the subsequent report.
Also, as an official, if I was asked to report on progress, that would include, to the extent the information was available, an indication of whether or not we had achieved a target, an objective or a policy goal that had passed in the previous couple of years.
