Bus man 40

Got unit 4 aos 1 recently, wondering if I am able to get a 42+ with these SACS so far:
Unit 3 avg was 90% ( top 5 ranked)
Unit 4 AOS 1 was 84 ( lower than I was hoping, definitely dropped in rank)
My cohorts pretty weak, so that why I’m asking since I’m not sure I get a 42+ scaled with that 84 sac
Thanks!
