I have seen in some blog that Prayagraj maintains good punctuality and you are contradicting here.
I can accept marginal difference of few minutes since the data entry is manual but dont foresee huge discrepancy.
I have followed the trains crossing at each inbetween stations corss check with there distance and time taken many times for 3-4 trains running within a span of 1 hr and to me the data looks to be reliable more than 90% if not 100%. Thanks.

and yes Prayagraj usually maintains good punctuality end-to-end for most of the days, barring some few days where delay is to the tune of 15 mins(acceptable)

Sir I was a frequent traveler in Gwalior Barauni mail both ways for years. many times its status in TE was updated just 30 mins or an hr delayed whereas it used to run hrs late and reach Gwalior altogether 3-4 hrs delayed whereas TE always used to show sometimes on time and other times just a meager delay of 30-45 mins. Many times I have given feedback using the feedback link but nobody responded ever.

Can't agree more to this, I have personally seen data fudging to the tune of 30-45 mins, while I travel and see the train enquiry data vis-a-vis real location of train, at least SIMRAN was more reliable as that showed the time computed via GPS location of loco and not just the time fed manually in system by operators.
