Sure. The method we use to calculate the CPI hasn't changed significantly in as long as I can remember. What we do periodically update are the weights of the various commodities that we use to compile the CPI.
For a long time we did this every five years. A few years back we changed to doing this every two years. As soon as the pandemic hit, we changed to updating the basket every year. We really started our last basket update just earlier this week. It will be applied to the CPI release we have coming out next week.
