Need Progression For Double Dozens Pattern Killer

[lb_like_y]

Hello guys, first i want to apologize for my bad English, is not my first language sorry for this.

So, my idea is to Bet on Double Dozen to kill pattern. The problem is the progression is too high sometimes and my bank can't stand it. Here is the method. we chose pattern who want to break. I chose 1 3 2 = this is dozens.. So my first bet will be on dozens 2 and 3. if 1 appear i bet on dozen 1 and 2, if 3 appear bet on 1 and 3 if 2 appear i restart. So my question is did you have progression something like  9 of 2 hits even chances. Again sorry for my bad English i hope you can help me. Merry Christmas from Bulgaria.
