The maximum potential benefits of any insured worker in a benefit year are the lesser of:
(1) twenty times his weekly benefit amount;
(2) one-third of his wages for insured work paid during his base period.
If the resulting amount is not a multiple of one dollar, the amount must be reduced to the next lower multiple of one dollar, except that no insured worker may receive benefits in a benefit year unless, subsequent to the beginning of the next preceding benefit year during which he received benefits, he performed "insured work" as defined in Section 41-27-300 and earned wages in the employ of a single employer in an amount equal to not less than eight times the weekly benefit amount established for the individual in the preceding benefit year.
