(b) For purposes of administering this section, the board shall have the authority to do both of the following:

1. (1) Establish and implement factors and assumptions necessary to calculate and compare the benefits payable to an eligible member. Those factors and assumptions may be based on information reported by the employer, including, but not limited to, all of the following:

   1. (A) Base hours.
   2. (B) Actual earnings.
   3. (C) Annualized pay rate.

2. (2) Review calculations that were performed using the factors and assumptions described in paragraph (1). If the board determines that an employer failed to identify part-time service performed, the board shall consider that part-time service to be performed in a part-time lecture assignment as defined by the employer. If the board determines that the required information reported by the employer is inaccurate, incomplete, or the factors and assumptions were applied incorrectly, the board may recalculate the allowance payable to a member using additional factors and assumptions that may include, but are not limited to, all of the following:

   1. (A) Base hours.
   2. (B) Actual earnings.
   3. (C) Annualized pay rate.
