Looking at the TT it seems like some problem.
VSKP - BZA is relatively slow.
BZA-Renigunta at 84 KMPH Avg Speed is much high but its doable since TN when departed on time overtakes Narayandri which means it crosses Gudur just after GT around 4 AM but its a huge tasks considering OT of TN.
Renigunta - JTJ - With mere 50...
more... KMPH Avg Speed seemsto be very low for premium train.
JTJ-YPR with whooping 102 KMPH Avg Speed is not at all doable. We also take into account that KJM-YPR itself most trains take 30 Mins.
So, i expect some tweeks in TT for intermediate stations.
