8OR9 read the system, understand the premise, then throw it away.
If you are betting $25 units in the pre-stage, determine how many chips you wish to use. I personally use 7, so that would be $175.
Disregard the Fibonacci back-end and use a Labby.
You bust the 7 chips, all you no win is 2 chips @ $100. You construct a string 1-1, which in all honesty you should be able to resolve within 8~10 bets, so it need $1000.
Alternatively, if you don't want to bet $100 units, construct a string consisting of $50 units, 1-1-1-1, now you need even less.
If you decide to use a pre-stage of 5 chips, busting that will cost you $125, then construct a string of 1-1-1-1-1-1 ($150).
Repeat the above using a pre-stage of $100 chips, bust it, and construct a string of 1-1-1-1-1-1 each representing $100 units.
Like I say earlier in the thread, YOU design / play it to suit yourself, your composure / bankroll, nobody should ever blindly follow any negative progression as written, come on man...
