Preflop Elasticity

I feel like most players drastically underestimate how big an effect preflop sizing has on their continuation range.

Compare this BB defense vs 2x and 3x. The difference is night and day!

BB vs UTG 2x

BB vs UTG 3x

Perhaps a more interesting question: is there some formula that can roughly predict BB defense% by RFI sizing?
