Pressure doesn't impact my fishing routine, as long as people aren't in my personal space and I have the space to do my thing. With that said, I think @Pat Brown said something which was maybe overlooked but is also my observation at least in central NC where we are. Unpressured fisheries tend to be full of small/stunted fish. Anecdotal, but he and I both seem to have observed this in various places, in my experience small private ponds which are everywhere around here seem to be like that.
Also, I think the fish learn the lures and react to that more than anything else. If you hit them with the frog every day for a week, you will see a diminishing return. Switch to a fluke, etc., and you're back in action.
Last thought- I have a theory that heavy pressure impacts their feeding patterns. On my home lake, it's electric only and you have to access through the marina which closes at 7p. If you happen to live by the lake and can slip a kayak in from private land, rumor has it 🤫 that the bite turns on some evenings between 7-8p and you can have a beautiful evening alone on the water and get some serious fish to bite, even though it's a very heavily pressured lake with regular tournaments on it during the weekends. Totally different body of water when it's 'closed', but the same fish...
