section to a disabled child shall not exceed percent of the compensation payable, at the time payments of the allowance fall due, to the judge holding the office which the judge last held prior to discontinuance of service as a judge. The amendments to this

section made during the 1991–92 Regular Session shall be applicable to any retired judge who elects to be subject to the amended provisions of this
