The big challenge will be in taking a look at the old school baskets. I think the biggest challenge is that there were commodities that were sold in the 1980s that may not be sold now, like VHS cassette tapes. This is similar to the commodities that are sold now that didn't exist in the 1980s, such as streaming services.
I honestly couldn't give you an assessment of the time it will take to come up with those estimates.
