Wait what are you aiming for? Could you give me a screenshot of how you're doing? I just searched for an hp fire spread on google, or you could try experimenting on "psypokes hidden power calculator" you can search that on the web. A flawless ditto should be used at all times, since you don't have to worry about the 31s on the ivs, and you should do your best to knock out all roamers before you attempt to rng on hg ss, makes it easier. Without roamers, frames tend to be from 1 to 3. But with roamers, it sometimes advances to 5, which makes it difficult to hit. good luck! :)
