A little information before I go into detail.
The fishing 'mini game' has 5 positions, 10 o'clock, 11, 12, 1, and 2 o'clock.
Positions 10, 12, and 2 are the main positions players will recognize. Your goal is to move the rod the opposite direction the rod is facing to deplete the stamina of the fish while at 12 o'clock you back off. 11 and 1 o'clock can appear with any fish, but high level fish will use it more often. The rod only remains in the 11 and 1 o'clock positions for a moment, but it's purpose is to trick the player into reacting early so the fish can regain stamina.
The slower the FPS the longer the rod will remain in these positions giving the player more time to reduce the stamina of the fish before it changes positions again.
For example:
Let's say that 10, 12, and 2 o'clock lasted normally 1 second, and 11 and 1 o'clock lasted 0.25. If you cut your FPS in half you could get (guess work) 2 seconds for 10/12/2 o'clock and 0.5 for 11/1 o'clock.
10/2 gave us a total of 2 seconds before while 11/12/1 gave us 1.5, with the reduced FPS you now have 4 seconds with 10/2 and 3 with 11/12/1.
These are all made up numbers, as the time it lasts in a certain position is random, but this still gives us information. With a lower FPS the player will have more time to lower the stamina, but the rod will also remain in dead zones longer as well. For the normal player this gives them more opportunity, but for the botter this actually slows them down. This is because a bot doesn't need to worry about recovering the stamina of fish, and since the game is forcing a lower FPS they are in the dead zone longer making fishing slower.
SE did this for the fisherman who are trying to fish more challenging fish, like Hakuryu, Matsya, or any of the legendary fish available in the game.
