Where is my shiny luck.. at this point I’m 0 for 80 raids now.. I cry 😭 back 2 back 100% Tapu Fini

At this point it's kinda funny, the past 5 or 6 five star raid bosses have been giving me terrible luck in terms of shiny luck, I've been doing up to 15 to 25 raids per boss and gotten no shiny, I mean at least I got back to back 100% 😭😭
