At the time fixed for the hearing, or at such time or times to which the hearing may be thereafter adjourned, the legislative body shall consider the objections to the reassessment and in its discretion informally direct the revision, correction or modification of such reassessment in such manner as is most equitable to apportion to each lot or parcel of land thereby benefited the amount of the actual benefits derived from the work.  When the reassessment is revised, or corrected or modified so as to comply with the judgment of the legislative body, then it shall pass a resolution confirming the reassessment.
