I'm at 78/80 ss logs * just started 5 days ago or so.
All i can say is that it's very costly if you want to maximize your efficiency in sightseeing.
I would cycle thru every zone with the current time frame taken into account everytime it's 12:05am,8:05am and 4:05 pm
If it's not the correct weather then i go on to next area. It costs me 3-5k gil for each rotation as an alternative to just guessing.
I went thru 100k gil already just from SS log teleports.
So i really do encourage that se get on with the weather npc already.
If you ain't got the dough and atma grinding patience then SS isn't for you.
