You’re basically talking about net present value at that point, again viewing the present as the correct valuation context. Past people not needed. Maybe “training” our extrapolation paradigm on the past people problem could lead to a better approach, but I don’t see why a priori. You get more mismatch between the training and test set. And that’s not even what we are doing here with price-adjusting an aggregate.
