sorry that journey time of your imaginary train is 1.35min not 1.45min that also more compared to Train 17225/Amaravati Express (PT) which takes 1.10min with stop at Annigeri. Actually previous i considered arrival timings but 17225 have 2min stop at Gadag jn.
so conclusion is 17225 being express takes 1.10min between GDG-UBL with Annigeri stop then this Imaginary SF should takes less than that i think so please check what changes you can do in speeds between GDG-UBL
