@Mmtfa There is benefit to applying larger lots, but you should pick a unique number like 93 or 122 - larger the better. Because allotment happens at each lotsize, if you are the only one, you can get assured allotment instead of going into lottery. 90 lots is a round number and others do tend to apply in round number lots, so chance of being sole applicant reduces.
Also given this subscribed 5.5x in BHNI (as per normal number, though some stats are suggesting 3.5x), even 3 applications in a unique lotsize would have been enough to enter lottery and get assured allotment.
