[...] There are not many years within the historic period of record that illustrate the impact of shifting the start of the apportionment year from January 1st to November 1st of the preceding year. [...] Alternative variant 504a isolates the effects of the apportionment shift by only changing the start of the apportionment year relative to the baseline model.
