Why can't I get a shiny?

I got the Shiny Charm, decided to do some shiny hunting, gave up on the Masuda Method, and headed off to Resolution Cave to catch a green Golbat.I decided to stop at the fishing stop first, because that was where I caught my Dratini. I figured I might as well try to catch a shiny Dratini while I was there. I got Magikarp instead, so I just chained it until I got a shiny.I was feeling good about myself, and decided to make things interesting for myself by shiny hunting everything I could. I headed to Route 2 to catch a Growlithe, but got sidetracked by a Rattata. I want a shiny. I’m doing what I did for magikarp, and I don’t know what’s going wrong!Let’s start with my Pokemon:My ace is Scizor. It knows False Sswipe (Because I’m feeling merciful to those stupid Rattatas), as well as Flash Cannon, X-Scissor, and Brick Break to KO non-shinies. They’re all lower than level 12, so I don’t really care about damage.

I have counted all the successful calls up to the 70th.

I am far past 70 Rattatas summoned, but no shiny. What am I doing wrong? I keep switching so they don’t Struggle, and I should be at peak efficiency. It’s taking way longer than Magikarp.

You got lucky with the Magikarp, I guess. You’re not doing anything wrong, just not the best luck. 0.15% is a pretty low chance, and players can spend a lot of time trying for a shiny.
