sHNI and bHNI allotment experience in IPOs this year

Hi folks, would like to know experience of people who have tried allotment through sHNI and bHNI route this year.

What was success rate observed against no of attempts in Mainboard IPOs where this approach was taken?

P.S. One issue with the way subscription data is shared by exchange is that it is not possible to know the over subscription at application level, they show data only in no of shares. However, an assumption of no of shares per application with over subscription data shows that generally probability of allotment is higher in bHNI then sHNI.
