Cannot speak for what works for others. But from teaching others about computers I learned this. If shown how to do by others the lesson is soon forgot. If it it learned by self instruction it never leaves ones memory.

I used to fish with a guy that bought the most expensive GPS/FF combo he could find. For sport fishing he was employing something you would only see on a commercial fishing rig. During an outing he revealed that he just left everything in the " auto " setting. Spending about 15 minutes with the settings I set it up much better than the "auto " settings. The improvement was dramatic. Next trip with him I noticed all the settings were back to "auto ". His explanation was it was just too confusing to him.

He was just too lazy to learn. He tried to make up for that defect by spending piles of money on his equipment. Needless to say this process never did one thing to improve his fishing acumen. He has since moved and we no longer fish together. I would venture to guess if we ever did happen to go out on his boat in the future.
I would bet the ranch that things won't have changed much if at all. Big shiny head turning boat and rig. Biggest baddest most expensive FF custom in dash installation and not a clue as how to operate the thing.
