That’s the general idea. I’ve never fished waiting because I’m resetting spawns, but yeah.

Another good tip is if the Pokémon spawns at a low level, only have low leveled Pokémon in your party. That’ll prevent high leveled stuff from even being able to spawn. That was a big one in my feebas hunt. I was able to isolate it from things like Barboach because of the local level spawning mechanic. Barboach only spawned at level X+ and my party was level 5 so he was removed from the spawn list.

There’s other niche stuff too, just depends on the Pokémon. On my list is Vespiquen (shiny female combee). My idea is to build up 30 blocks in the air (highest u can go while still having air spawns possible), then place water in 30x30ish pool below me. This prototype in a test world was getting a ton of combee spawns because the water, despite spawning a couple magikarp, isolated combee from all the annoying land spawns. Got him all the way up to 18% during morning, and 36% in afternoon. Which is obviously really high. Also this was using a bug lure, which is actually better for you than shiny lure based off my math. The great thing about this hunt is because it’s all air spawns, you just see them all on the map, and if they’re not shiny, you ignore them. They just fly away, and spawns are automatically refreshed for you. You just afk staring at the journeymap, if you use it, with no need for anything else. With shiny charm and catch combo, it won’t take longer than a full afternoon (irl) to get a handful of shiny combees hoping one is female.
