(3) the experience of other insurers or rate service organizations; or

(2) The loss costs applicable to employments classified under sections two hundred twenty, two hundred forty and two hundred forty-one of the labor law, provided such employments are classified under each of said sections, shall be adjusted to reflect the payroll limitations required by this section as they separately affect such rates for work actually performed within each of the following geographic territories:

For all other purposes, the superintendent, except as otherwise provided in this chapter, may promulgate regulations defining loss costs.

(h) A loss cost filing shall be deemed to be a rate filing under this article.

(i) Nothing in this section shall prohibit the application of payroll limitation provisions at the discretion of the superintendent, provided such programs were in effect prior to the effective date of this subsection.
