@Kalimpong Suppose HNI oversubscribed by 400x.
Then allotment will be if 2 lot application received suppose 50000 . So for 2 lot number of lot allotment will = 2* no of application (50000)/ 400=# ( Rounding if if below 0.5 then 0, above 0.5 will 1),
If 3 lot application 5000 then = 3* no. Of app/400= &,
So, lottery will done for 2 lot applicant and number of lot allotment is #, same for each lot allotment.
For sure shot allotment one can subscribe 400 lot minimum,
If any applicant apply ( only 1) application above 200 lot then it gets allotment surely
Hope your view may clear by some way.
