Yeah, some of this like how many unis at how many spots, cooldown timers, a database of coords to fish at, etc is beyond what I would ever do.
I believe people should actually fish and learn some things themselves. No interest in creating a point and click to win reference. Same reason I have never done videos for this game. Quite frankly with existing videos and sharing markers much of this already exists just not in a singular reference. Yes, many videos suggest fishing with hooks that are way too small when bottom or float fishing, people need to actually fish, play the game, try different things and learn for themselves.
I've read comments over the years that a uni can't be caught at x time or on x lure because it's not on the Ubersheet. I've had people argue with me in-game recently that x spot is the best place to fish at x location because that's what they saw in a video. I had someone try and tell me you could only catch uni marble trout on a rainbow spinners, lol. Anyone can make a spreadsheet, anyone can make a video. Any such tools IMHO are intended as and should be used as a guide at best.
With the amount of new players power leveling and relying on videos or other tools the fishing/gaming IQ in-game is at an all-time low. Too many have no clue how to actually play the game or 'fish' they just mimic what they have seen in a video. The Ubersheet has always been purposefully a non-exact reference to help guide a player but not to practically play the game for them.
