"I found out mathematically which types are best defensively!"

A while ago while scrolling the dual-type page on Pokémon DB, I noticed something. It said "By cumulative score". But it only had the top 10 for worst and best. I decided to calculate all of them. Basically cumulative score is a method of seeing which type combinations are best defensively. You start by looking at all the matchups offensively against your type. Let's take Flying/Grass for example. We start at zero. we add 2 'points' for every 2x super effective hit. 4 points for 4x, 1 point for neutral, 0.5 for half, 0.25 for quarter, and 0 for immunities. The type with the least points is better according to their score. Grass/Flying got 22.25. I have never seen someone on the internet calculate all of them, so I decided to be the first. (Unless I am not).Here is the Document for my Data:DocumentIf there is any questions or errors you noticed, don't be afraid to contact me. via /r/pokemon https://ift.tt/Uq7v2Mx
