Thank you very much for your question.
No, we do not review the CPI data. Of course, we adjust the seasonal measures after consulting with experts, but the results are the results and we usually do not adjust them.
There are several reasons for that. The first has to do with quality. The second is that the results are used in many different ways, such as to establish pensions and wage agreements, among other things. It would cause problems if we were to continually adjust the data.
If there is a problem with the quality of the data, we correct it immediately, but we are not in the habit of systematically reviewing the data, so the answer to your question is no.
