1. A method for calibration of a capacitive touch digitizer system, the method comprising: detecting patterns of signals from a plurality of different touch events and a plurality of different lift events over a course of user interaction with the capacitive touch digitizer system, wherein the patterns of signals are outputs from a digitizer sensor of the capacitive touch digitizer system; determining a number of times that a pattern of signals from the patterns of signals detected is repeated over different events; identifying that the pattern of signals that is repeated represents a pattern of signals from a lift event, responsive to the number of repetitions being above a pre-defined repletion threshold; and defining a map of offset values as the pattern of signals that is repeated above the pre-defined repetition threshold.
