Agreed, but I'm talking about comfort of catching 3 PM Slot Premium Trains from Nizamuddin.
Arriving at 2 PM at New Delhi doesn't exactly give me a comfortable buffer to reach Nizamuddin by 3PM especially if my next journey is a longer one... Secunderabad Rajdhani/Duronto, Chennai Rajdhani/Duronto or anything else in that slot.
New Delhi Arrival at 11 AM from Prayagraj gives one enough time to have lunch and proceed on with next long journey.
2...
more... PM Arrival is too risky and too rushed.
