@GJ Eighteen , what
@Smile✍️ said is absolutely correct.
The registrar doesn't know if all that all the 20 applications belong to you and you must be allotted as it is subscribed 7x.
For a registrar each individual application is unique and each one has 1/7 based on 7x subscription.
To give you an example there was an IPO which was 5x and I was allotted 0 on my 5 applications.
And there was another one which was subscribed 50x and I was allotted 2 on my applications.
Hope this example clarifies.
