Bihar Sampark Kranti - ECR Don ka ticket Confirm hona mushkil hi nahi, namumkin hai. - Somanko

Hi, I have to make a journey to Bhopal most probably on the 5th of July. As Shipra is filled, my options lay twofold :-
HWH-JBP followed by a subsequent JBP-BPL journey or a HWH-BSP followed by a BSP-BPL journey....
My questions are :-
a. Which is the better proposition?
b....

What is the average delay of 11448 at JBP. Will it be possible for me to catch the HBJ intercity departing at 16:10 PM at JBP. Based on the average delay showings of 11448, I feel that the buffer time in between at JBP would be a little too less, if any! Should I risk going for the HBJ intercity or do I wait for the JBP-INDB overnight express? It is the engagement of my friend's sister, so I have to be positively in Bhopal by 7th morning.
c. Or should I go by the BSP-BPL route, if then so, please suggest me a proper chain that would be practically viable....
Thanks!
