i've been looking at this idea recently and it's been doing ok.
i've probably run it through about 800 spins and the results are promising. it could be a flash in the pan, but we'll see.
basically i bet that the dozens don't show in the order 111222333. i use a 9 spin cycle and then start over again.
hermes was looking at a similar idea, with 112233 and i've just added a twist.
i use the leveller progression that hermes uses too!
we bet 1,2 and then 4. i also incorporate the principle used in oscar's grind, where we only bet to gain 1 unit.
so, if the first bet loses we're down 2 units. we then bet 2 units each dozen. if that loses, we're down 6 units. the next bet is 4 units each and so if this wins, we're down 2 units and so just bet 3 each.
i can post examples if required. any testing or alternative progressions would be most welcome!
cheers.
some examples from actual spins:
30 bet dozens 2/3, win, so see out the 9 spins. we're aiming for 1 unit per 9 spin sequence.

6 L -2 units
29 bet 2 units each dozen, W, back level, so back to 1 unit on each dozen.
1 L -2 units
1 bet 2 units each dozen, W, back to 1 unit.
27 W 1 unit profit, stop betting.
