Apple pushed an update in iOS 13 which brings the latency on the Pencil down to 9ms. Which I remember vividly because it's when latency on the Pencil subjectively "went away" for me. Especially for tight loops in cursive, on iOS 12 the line would 'catch up' with the stylus, but at 9ms I don't perceive that. Edit: crosshatching is an even better example of a technique which feels completely different at 9ms rather than 20ms.
