Cant understand "to some extent it matter"???
Thats because even with no Scheduled OT by Raj, all other GR get OT-en by Raj, making avG delay on higher side..
While this GR do hav Sch OT in between Gaya & MGS, but afterwards, its heavily slacked (as Slot)..& even then, its 1-2 hrs late ARR @ ANVT is quite equivalent if other GR arrive 4-5 hrs late @ ANVT!!
