Provided, however, that in calculating the allowable state tax growth factor for any fiscal year, the same total for Massachusetts wages and salaries for a calendar year utilized in prior calculations involving said calendar year shall be utilized in subsequent calculations involving said calendar year, notwithstanding periodic adjustments by the Bureau of Economic Analysis of the United States Department of Commerce made in total Massachusetts wages and salaries for said calendar year.
