@Venkatesh Akana For SME IPO allotment is done on proportionate basis, which means allotment chances increases when you apply with more lots.
50 lot application has more probability of allotment as compared to 10 lot application, so most of the applicants try to apply with maximum lots as per available funds and own risk appetite. Refer below thread for more details

Note: For SME, any thing above 1 lot is NII/other. There is no SHNI or BHNI Quota.
