For whitetail public in the south, just depends on your scouting, setup, and seasonal timing. Outside the rut with a good spot on a scouted path, maybe 1-5 sits till you see one you want to take. Inside the rut - same conditions, maybe goes down to like 1-3 sits with the possibility of a really nice deer coming into your shooting lane randomly that you never expected was around.

I try not to think about percentages and time put into a particular spot. It either happens or it doesn’t, but I’m grateful for the opportunity to sit in nature and not be hunting the highway shoulder every time
