I like the mongoose progression so much that I've engineered a system around it. This system is intended for play on the BetVoyager no zero RNG. For those of you who distrust or dislike RNG, sorry, but if you read the BV randomness control section you might just change your minds. Anyhow, we are betting 12 sleepers and 6 of the hottest repeats for a total of 18 units, an even money bet. I would track until at least 55 spins with 12 numbers still sleeping, the more the better. Approach the betting like a flat bet and apply the mongoose after a win, like so:

1st bet 18 units

2nd bet parlay 36 units

3rd bet 2-step marty, so 18 and if lose, then 36

4th bet 3-step tweaked marty, so 18 and if lose 18 again, if win the second restart on the 1st 18, if lose 1st and 2nd 18, then bet 54.

So we risk 1 unit(18) to win 5(90). If we lose on the 1st, 2nd, or 4th bets we lose 1 18 unit bet; if we lose on the 3rd bet we break even. We need to win the 1st 2 bets to be in business, after that we can lose 1 of the 2 3rd bets. We need to lose 3 in a row to lose the 4th bet.

We need to win 4 out of 7 bets to be +5, whereas we would only be +1 flat betting.

A little more explanation in case it's not clear:

If we win the 3rd bet we move to the 4th. If we lose then we double up (marty) and try again. If we win then move to the 4th; if lose back to start.

If we win the 4th bet we are finished (+5). If we lose we bet 18 again. If win go back to the previous 18 bet. Basically we need to lose 2x in a row to bet 54. Hope this makes sense.

So the idea is that we are using a bad-ass positive progression to win on an EC bet, only it's a supercharged EC bet because it uses sleepers and hot numbers. A little candy for GF fans and haters alike. I'll be testing this when I can; feel free to post questions or comments. If you despise RNG that's fine, but you don't need to tell me about it.
