What is the accuracy of touch.timestamp and touch.location?

[lucast4]

I am developing a program that needs to collect precise and accurate data (i.e., position and time) regarding touches. I am collecting those data using to following code:

data = []
x, y = touch.location
t = touch.timestamp
data.append((x,y,t))

I am using this on the regular Ipad (6th gen)

How precise and accurate are x, y, and t? I looked at the docs (http://omz-software.com/pythonista/docs/ios/ui.html#ui.Touch), but I cannot seem to find this information anywhere.

Thanks!

@lucast4, suggest looking for the information in general Apple UIKit docs first (e.g. this). Location accuracy should be 1:1, timing accuracy could be as well.
