"Expect" to see? None.
If I go sit on the neighbor's right of way, I expect that I will eventually "see" a deer even if it takes several days or a week, even if it's just running across at 20 mph.
The last time I had genuine expectations of seeing deer for sure was in the early 2k's bow hunting. I had a spot were I knew if I was in the stand 2-4 evenings in a row, doe would come down the hill and walk past me at least one of those evenings. Never shot one, it was always right at legal light (or then some) and I never felt comfortable trying to track one in the dark. About that time maple syrup lines went up and changed their travel pattern and my great spot was no more.
I started deer hunting in 1985? Back then a hunting "season" may have been 2-3 days. I didn't get a shot at a deer til 1990-91? Didn't kill one till '93.
Now my "seasons" are 7-10 days of gun. 3-4 days of bow. MAYBE 2-3 days of muzzleloader. My success rate's about the same now though despite more days in the field.
I shot a deer this year, last one before that was 2018-2019?
(I am also the "luckiest" hunter in the world

, in between those years I shot at and missed 4 deer. "Missed", meaning I hit branches and other vegetation deflecting shots. I can shoot at a deer in an open field and hit the one damn little twig thing growing in it. I've had scopes lose their zero for seemingly no reason, I've had a scope mount fall off a gun after being rock solid for 50 years prior. I'm blessed in that way. lol )
