QUESTION ABOUT THE LABBY SYSTEM???????

i have a question doing a labby system

say i have a

10 10 10 10
10 10 10 10
10 10 10 10

and i win the first two bets my line1 is cleared so now its

10 10 10 10
10 10 10 10

i lose bet 3  and the lines are now

10 10 10 10 20
10 10 10 10

the next bet would be 30?

and if that loses then the line would look like this

10 10 10 10 20 30
10 10 10 10

so say the next bet is 40? if that pushes then the bet after would be 40 again?

also if you lose bet 1 and the line is 10 10 10 10 20 if you win the next two bets youre left with one 10, do you just bet that 10 or just grab a 10 from the second line?

heres a full explanation of the labby system
