Because there is a lot of interest on this subject and there are many struggling with the many possibilities, I will explain a little bit more:
First of all, my aim is off course to walk out of the casino with a decent profit most of the times. This is off course in contradiction with the ultimate "safe way" of play, therefore I try to find a balance between them. the nice thing with the labby is that you are warned in due time for dangerous situations that can occur, and in these moments I will start palying very carefully, meaning change my bets, transfer figures to other even chances, and last off all spreading the Labby(which is unadvisable, because it means that you have to win more bets to get out of it).
I start playing with 0,1 on one even chance, the one that shows the least large series (so the most choppy one). my bet selection is playing on the brake of series of 1, 2 and 3. If a series of 4 appear I stop betting till the series brakes. Then continue the betting. In this way I don't have any problem with 68% (theoretical appearance % of series of 1,2 and 3) of the charts in terms of losing a bet in the labby. When a series of 4 or longer appears, it means my labby contains 2 more figures. The dangerous chart is therefore the appearance of alternating series of 4 and longer. After occurrence of 2 alternating series of 4, i will transfer half of the figures to another even chance that is the most choppy to divide the risks.
As everybody should know by now, I combine mini-marti with The Labby, meaning, I play pairs of decisions with 1 and 2 unit bets. If I lose 2 consecutive bets My labby gets 2 new figures: example:
When I lose 6 bets in a row my Labby is: 0,1,1,2,3,3, next bet in pair: 3 units, if lost 6 units, if lost labby is 0,1,1,2,3,3,4,5. It is just an example because as stated before I would have already transfered some of the figures to another even chance, or sometimes even to both other even chances.
another way of lowering bets without spreading the Labby is the Low/High principle: after you lose the first pair and The Labby is 0,1,1,2, your next bet isn't 2 and 4, but again 1 and 2, so repeat of the first betpair until you win, then continue like normal (first and last number of The Labby added) Low stands for low bet, High for high(=normal bet).
So, you have a lot of possibilities to stay low in the bets during bad streaks, without spreading the labby into more figures needed to stay within the 1:2 ration needed to close the Labby. The way I play with pairs it means you need only 1:3 wins to close it (actually 1:3 plus 1 bet). So for example when you play on R then you need only in 50 spins 13 R to close it. That is already very close to the worst expectations in terms of Ecards. (see the figures given by Muck) and without taken into account the many possibilities you have to keep the bets low.
Judging when to take countermeasures when there is possible danger for a bad streak is unfortunately not something where we can give rigid rules for, it will be personal decisions.
One thing I want to emphasize is that dividing losing bets in more then 2 figures should be avoided as long as possible, because that will change the 1:2 (or in my case 1:3) . But in the 1:3 it means that if you divide in 4 figures you still have an advantage of 2:3 W/L, but for me this would be the last countermeasure I would take. (didn't need it till now).
Off course , who knows, one day we will see 100 spins, and only 10 blacks, then also this strategy will fail, but the chances are almost 0, and we still are gambling.
with a BR of 2000 units, in Theory you should overcome any bad permanence. The Labby will always ends, how longer the session, how bigger the chances, because the Ecards will become smaller according the Law of the large numbers.
I hopes this helps,
