I understand the concept of creating lines. For a 10 better the starting line would be
5-5-5
We are going to chase a three game series.b The first game is -170, the second game is -180 and so also is the last game.
This is the situation
If the first bet wins then the next bet on next series is going to win 5

2nd game
if the first bet loses then the line will change to 5 - 5- 5-17
the next bet would be to win 22, so would lay 39.60
if this bet wins, then the bet for the next series is to win 10

3rd game
With the loss the line should be 5-5-5-17-39.60
here is where i need help understanding
so is it correct to say the last bet would be to win 44.60, which means to lay 81.
now if this wins then does the next bet in a new series start out with winning 22 or 17 plus 5. if this is the case it would seem very hard to close out the line since you would have to get on a roll of winning two bets in a row. if this was not done, then the number to the right would continue to increase and increase until you hit some limit.
