Ask HN: Undo/Redo – Two- or three-finger REDO gesture?

Recently ProCreate was lauded by Apple for their undo gesture (two-finger-single-tap). https://procreate.art/insight/2018/take-our-undo-gesture

The Redo counterpart is a three-finger-single-tap, which imho is technically difficult and hard to perform on a small screen.

A modified implementation could be: Undo: two-finger-single-tap (same as ProCreate) Redo: two-finger-double-tap

What are arguments for or against two-finger-double-tap to undo?
