GKP halt should be atleast 10m and 15m if acc to an ACSF TT very much like NJP. ANVT CNB 90kph easily possible since RNC GR does 90(among normal SFs) with RT at CNB and PNBE RAJ does 94 in NDLS CNB. So no need of slack till GKP. Although CNB LKO should be less than 60.Try to implement these changes. Green flag buddy
