I think we are safe to say that a doublestreet (line) can not sleep more than 80 spins.

No, no kav, we are not at all safe! Right after exactly 80 spins the probability that the double street wakes up in the very NEXT spin is 6/37 or 6/38. No more no less. The Goddess of Fortune has not placed a mystical limit right after a certain number of spins. Better safe than sorry. It is simply a question of TIME, before a certain event happens. It may happen today - or after a zillion more spins. Any mathematician may confirm that.

Dane,

Very interesting comment.

I didn't say that after 80 spins the probability of a line changes. I said that it is safe to assume that none will observe in his life a line sleep more than 80 spins. As it is safe to assume that none will see in his life a number repeating 10 times. As it safe to assume that none will observe 50 Reds in a row.

These are events of extremely low probability.

You talk about the independent probability of a spin. I talk of the probability of a series of spins.

The use of these observations and statistics is not to wait for them to happen and then bet the opposite the very next spin. That would be impractical anyway - waiting for a line sleeping 80 spins. The use of these observations/statistics is to determine the worst case scenario,

Betting on something that is missing, or betting the opposite EC after a series of consecutive spins requires special techniques. The depth of something that is missing is wide open. It can vary from a few spins to a lot of spins. A consecutive run of an EC can vary from 2 spins in a row to 12 spins in a row, and rarely even more. Since we don't know how far the missing will go for, or how far the same EC will keep turning up, it is wrong to keep betting what's missing until the bank roll runs out, hoping that the missing will finally show up.

The same goes with betting the opposite of a series of the same EC. Bet red after 5 black and the black can keep going to 12+ spins in a row,

The best way to handle it is to predetermine for how many spins you will bet the missing, after a specific number of misses. The average missing spins for a group can be easily determined, by the player if he is willing to do his homework.

For example between 5 and 7 consecutive spins of the same EC, the opposite usually turns up in the next 3 spins. And that's all you need to bet. 3 spins. If it decides to stay on the same run, then you don't care because you will not bet more than 3 times. Your loss is limited to just 3 spins.

However the next time you encounter a 6 spin run of a specific EC, it highly unlikely that the 6 spin run will continue to become a 10 spin run once again. And it's almost impossible to continue the same pattern in the next encounter.

**A roulette cannot keep up the same exact pattern, each time it encounters a specific situation. **For a missing dozen or 2 DS's or 1 DS the average missing spins is longer. So all you do is adjust the waiting for the misses and the number of spins you will bet on it,

If you observe a missing dozen or column, and you happen to see it missing over 8 times in a row, see what happens in the next 5 spins. You will be surprised.

To summarize, if someone has a $10,000 bank roll and he is willing to stop after a $200-$300 profit, he may never lose in roulette again for the rest of his gambling life.

It's that simple if a player follows these instructions.
