There is two options here.
One is to stretch the progression and make it accept small loses in the middel and at the end, so the first bets win +1 unit or break even.
And the other solution after the last bet of the progression is to bet half the size of the total amount of the progression.
That way you could bet against 19 to 30 with the first option and from 30 to 33 using the last option.
But to build such progression you need to know your table minimum and maximum.
The table min is 5 and max is 5000
(Online casino using the same video feed over three table which have different limits, so I can consider this to be the same table with limit 5-5000)
