I haven't read the your thread but mind-energy's descprition of the experiment.
From a sceptics perspective the chances of both persons should be 50:50, when both of you have no skill in getting information.
You shouldn't be able to win it by chance. The results of chance guess work shouldn't bring you to a more than 1:1000 chance of winning. 1:100 might also be okay but no sceptic would accept a 50:50 chance to lose in facing a psychic.
Is their a diffence between a polaroid picture and a digital picture?
