@Sleepy For BHNI all applications are for at least 67 lots, but on allottion one gets 14 lots. Hence chances of allotments are more.
Will try to explain with example below
Suppose there are 67 lots available for BHNI category and 5 applications received. Then the subscription is 5x and each application will be allotted ~14 lot i.e. 100% allotment
In this case SHNI will be ~33 lots and if 5 applications with each 14 lots received then subscription will be around 2.5x and only 2 applications will be allotted with 14 lot each ( remaining shares will be distributed equally among this 2 application). Here allotment is 40%
This is my simple understanding and experts can confirm on this.
