The Apple Pencil is designed for extremely low latency and high accuracy to make it feel as close to writing on paper as possible. The API offered to developers presents predicted digitizer points and retroactively updates them in subsequent frames because even the latency introduced by a standard 60/120Hz draw loop introduces cognitive dissonance - your brain can tell something is off if you wait for the next frame update.

People are making a lot of bold claims with absolute certainty without so much as a test rig... how they can determine that such precision doesn't require any calibration or that using the old controller with a new screen is "accurate" is a very interesting question. I'm not sure drawing a few lines in one app is sufficient to draw such strong conclusions.
