Statistically every dozen should appear once in every 3 spins.

However, in the very short run (just like all equal chances), you don't often find an exact statistical distribution of chances.

In fact, aberrations of correct statistical distributions happens much more often than not. (In the short run of course).

In the case of single dozens, each dozen has an average **no show range**, from 3 to 6 spins.

Considering the YXX trigger, you fill the one dozen no show gap by either the Y or the X dozen.

Since the X dozen showed up twice , it is more likely that the Y dozen will appear in the next spins.

If it doesn't in one trigger, one of the next triggers will fulfill this premise.

That's according to HARRYJ, who unfortunately is in a very critical condition in a Johannesburg hospital.

In a way due to the short absence of one dozen, you have a 50% chance on two items that pay 2:1 instead of 1:1. The advantage is obvious.

This is perhaps y this system works so successfully, and I am glad you report flawless results in a real B+M casino.
