Scuttle fights

Hello!

I am Kindred enjoyer with around 150k points and 60 percent winrate, currently in emerald elo. Where i see i can improve my game is, scuttle fights.

To make it short, i believe 1/3 of my games are based on the fact I either win the scuttle fight, or i completely int, followed by int of, either my mid or top which follows me. The problem is, i don’t know when i can win the fight or i can’t… it just feels like coinflipping.

Does anyone have a spreadsheet of champions i should contest the crab against, or i should path away from them?

Edit; for example, i have learned i shouldnt contest Viego, he absolutely trashes me every single time. Thanks!
