Thereafter, during each succeeding fiscal year such minimum percentage to be provided from current funds shall be increased by two per centum over and above the minimum percentage required for the preceding fiscal year, notwithstanding any increase in the amount of the debt-contracting power of any such city during such succeeding fiscal years.
