I've made a simple tool to quickly check all 2^32 raid seeds in order to maximize drops. Currently I focused on Herba Mystica as it seems to be the most valuable drop. Turns out you can get as much as 10 herbs from a single raid! I found idea of raid seed injection interesting because it allows a single person with CFW to inject a seed (via PKHeX or cheats) and host that raid over and over for other people. You can e.g. help your friends to farm herbs quickly and make their shiny hunts much easier.
Currently I generated seeds just for Herba Mystica but if anyone is interested in different drops and/or shiny Pokémon just let me know here or open an issue in my GitHub repository (https://github.com/MewTracker/sv-research).
Herba Mystica (8, 9 and 10 drops): Scarlet Seeds / Violet Seeds
Ability Patches (5 drops): Scarlet Seeds / Violet Seeds
Shiny 6IV: Scarlet Seeds / Violet Seeds

filtering by raid reward count (you can filter for specific rewards)
filtering by raid difficulty
configurable game version, story progression and raid boost
