If there are loads if photographs...Yes, good point. If there are loads if photographs with just one large whole in the middle it would be simple to guess where the hidden location is.<br />Regarding the pattern I was referring for example to the Barabasi work based on cel phone data and the predictability of an individuals location to be at any time about 93%. This is purely based on the pattern of movement whether specific hotspots are covered or not.
