In a saltwater application and from what I've read most of your fishing being done on foot then most likely not gonna be very helpful. A few of the variables you state actually don't change. Yes the water level can change but where the fish are locating may have not. Color paterns for baits used probably won't variate much either. Bass fishermen don't rely on bait coming and going whereas in the salt you do. It's either present in said waters orbits not. If there is no bait on a given bass waters then most likely the fishing is going to suffer especially size and health of caught fish. Which a lack of bait could force the bass themselves to become more aggressive when one of our imitations is presented. If you have a log bass fishing and year after year when the water temps are 85 degrees and you catch fish consistently at depths more then 8' then that would be a great place to start your search for fish. If you catch fish on a certain lake with a certain color. Knowing this will allow you you rule out using colors that you've previously had zero success and again a good place to start. I can almost assure you that a large amount of pros use some type of log to know which presentations may work the best for certain waters they may come across. Do I think it's the greatest tool a bank fishermen could have, NO. Access to deeper water most likely isn't an opportunity you will have and be able to change any of the variables associated with it. Although logging which lakes have been successful for you at different times of day could narrow down the waters you fish at that time of year. Yes a lot of us recreational guys enjoy just being out on the water but to some fish caught and performance as you call it is the marker for how much fun they are having.
