I'm trying to use the Apple Pencil pressure values to draw a line of varying thickness. I find that the pressure spikes erratically, often showing full-force at the very end of a stroke, when actually there is no touch. Also the very beginning of a line reports as much higher pressure that quickly drops to something much smaller. And occasionally in the middle of a line when I am drawing lightly, I'll get one or two touches that are spiked really high also.
Is this a common thing? How do you prevent it? I will probably just start filtering the pressures and maybe tossing ones that vary drastically from one point to the next, but it should not be doing this, should it?
