The sections where Puru/SK dont run with 130 MPS is the only and best possible route. One cannot divert SK via GAYA as it is slower upto GAYA and longer. Same for Puru that KGP-ADRA-GMO route can be taken for fastest connectivity but that would mean TATA,PRR,BKSC would miss out to the only daily DLI connectivity. For Poorva to be taking the via BSB route the only reason was to bring it at same time arrival as 12303, nothing else. HWH-BSB and BSB-DLI are very well connected so dont understand why is it going via that route simply for wasting time. ALD outer is dangerous be it NYN,ALY,PYG but NYN side trains dont halt for hours on ALD pf.
