before JD shut down the first time, Doog did some stats on longest losing and winning streak at 49.5%.
I believe loses was as big as 32 in a row, and wins was 19 or 20.. i'm not 100% sure of the stats. its in the old JD thread somewhere.
Remember that this isnt simple 50/50. at 49.5/50.5, the max loss streaks will be longer than the max win streaks. (thus you can see the house edge in action, sortof)
RIght, that's actually an interesting point, a1choi, the longer the streak you're multiplying out, the more you're going to see that divergence between wins vs. losses multiplied out and getting bigger. Ie, as you say, you can observe the house edge in action.
