I think it would be much better to use some kind of Kalman filtering so you don't have the huge lag. You don't need to commit to permanent output immediately so it is possible to draw with zero lag and then smooth the output afterwards.

Yeah it’s a nice brush model but that is a huge gap between the input and ink.

Kalman filtering is what's used in GPS navigation apps, is it not, to smooth out imperfections in the raw GPS signal?

Yep. You can use it for estimating all sorts of things based on noisy measurements.
