Z-score 2.37 Safe betting system

[Colbster]

Here is one that I have been working on for a while that is showing some statistically significant promise (P score greater than 98%!!)

Bet selection:

Track all numbers until a repeat.  Begin betting that dozen using the progression below.  We will stay on this dozen until another repeat comes more recently, although not the latest to repeat.  What I mean by this is if we are tracking and we get a series of 17-34-34-17, even though the 17 is the most recent to repeat, the 34 repeats in its entirety more recently and we would bet the 3rd dozen, not the 2nd.  Whenever we get a new repeat, we delete all spin data prior to the farthest back occurrence of either repeat.  In the above scenario, we would delete the first 17 and every single spin that had come prior.

Progression:

I am using the Hollandish method.  Start by betting 1 unit as long as you win.  Once you lose, write down a 1.  Since we are betting a single dozen, if we lose again, we write a second 1, giving us 11.  If we had won, we would be at a new high and would restart.  If we lost both bets, we would move to 2s and continue writing down 2s for as long as we continue to lose.  After any win, we cross out the first 2 numbers in the line.  We always bet 1 unit greater than whatever number is the left-most of our list and write down the bets that we lose on the right of the number line.  Wins cross out the left 2 numbers and we play until a new high, always restarting at 1 at a new high.

Money management:

This has been returning approximately .5 units per spin in the short-to-medium term testing.  Draw downs have been in the range of 10-20 and I have been starting with a bankroll of 100 units and playing until +100.

I think I get the jist of it, but a sample session would be appreciated, especially something that would involve the special circumstance that you mention below. And also include the progression per bet.

Thanks

Any body else tried this? Very slow but working so far.
