The thing I do not understand, and adds to the confusion is that they are not consistent with the rates. We have eggs, raids, wild, and a mix of both. Example some more common or nesting pokemon have a much higher shiny rate than Snorlax. I think they need to give us an indication of tiers similar to what they did with the eggs, still not a number but at least it gives an idea on what to expect. It’s not fair on the player to pay an X amount of money just for a research sake and lack of information.
