Its a wonderful analysis, kind of rare at IRI where blogger go extra way to create self analysis by raw occupancy data. Ratio seems to be unique & display effort induced in Data!!
Overall DBRG induce 15% which can't be excused. NTSK could be termed underrated if train byepass Tinsukia without NTSK existence!!
It's a well known fact that NTSK feed to much extent to NFR trains, but collectively along with Dimapur, MXN & together with DBRG they make better impact!!
Honestly I don't even care about any single station much, the 4 imp stations of this route, i.e. NTSK, DBRG/DBRT, MXN, DMV all are major contributors to passing /originating trains. NTSK is traditionally more revenue generating because of its better connectivity with Duliajan, Namrup and eastern Arunachal regions like Roing Tezu etc. It also earlier had better road connectivity to places like Pasighat when Bogibeel was non existent, hence is still preferred by many people and armed forces personnel.
