Any way to Reduce TouchMove sensitivity so Itemtaphold fires more reliably?

[drb]

Touch 2.1.0-rc2

Is there any way to reduce the sensitivity of TouchMove?

I am using itemtaphold on Ext.List and it is very hard for the user to hold a finger still enough on an iPad 3 to register an itemtaphold. It seems that the touch move event gets fired at the slightest jiggle.

Thanks

I have tried the following, but I don't know if it is really safe.

The idea is to ignore finger movement of less than 5 in any direction.

        Ext.define('Ext.overrides.event.recognizer.LongPress', {
            override: 'Ext.event.recognizer.LongPress',
            onTouchMove: function (e) {
                if (e.absDeltaX < 5 && e.absDeltaY < 5) {
                    return;
                }
                return this.fail(this.self.TOUCH_MOVED);
            }
        });
