Really dig deep on what they are doing, they may think they aren’t doing anything special but there is probably something there. Are they getting out there at 4am while you are getting there at 8? Are they spending the whole day vs you are getting lunch back at the truck? Are they practicing good odor control, And so on…
Maybe switch to a shotgun rather than bow so that you don’t have such a tight distance limitation. Also, maybe sitting in a stand just isn’t your thing, I know I couldn’t sit in a place for more than a half hour without getting antsy and leaving early. Some people I know really are just lucky, my cousin from Wisconsin came out to do an OTC elk rifle hunt and he literally just walked in to a bull elk 40 minutes in to the first day and shot it.
Try a western hunt where you are doing more glassing and stalking rather than sitting in one place all day or even do a guided hunt or two and really spend a lot of time with the guide asking them what they are doing and why.
