I'm not sure this is a good idea, there have been at least 3 different batches of LCDs which slightly different touchscreens attached, with such thresholds we might end up with unreachable touchscreen points on some units. If I understand right, calibration won't help if for some screen locations ADC reading goes below/above these min/max thresholds on some specific units? If so there should probably be at least 10% margin in either case to make calibration useful.
