IPO Allotment and BSE.

For some reason I have been applying to IPO for 3 years. 70 plus IPOs applied. But for some reason if the application get filed to BSE, I never get it. It's not even like I got one or two... 100% track record of not getting any from BSE. The 15-20 that I have got are all from NSE. Is it the same for others? BSE me kuch to jhol hai. The recent IPOs of Mamata, DAMS, TransRail all got filed to BSE from UpStox... So I have already given up hope!!
