Playing in veteran mode when I loose, and then stubbornly refuse to change my choice, I'll constantly loose as the computer then 'correctly predicts I would play scissors' or whatever losing choice I've made repeatedly. Surely at some point it should think I won't be that dumb any more and I'll change my choice so shouldn't it change it's choice at some point too? Why does it always stick with it's winning choice? How many of the previous 200,000 rounds would have over twenty consecutive choices of scissors for it to always choose rock. Having "convinced" the computer I'll play scissors every time I can then win when I eventually choose paper. I can't get more than three consecutive ties though.
For some reason I'm reminded of Derren Brown recording for hours on end until he got twenty consecutive heads in a coin toss in one take.
