Is it possible having an Edge on single dozens with Standard Deviation ?

Simple Question, difficult Answer, I guess.  What do you think ?  Responses welcome.

My strategy is simple: Waiting for 13 spins and doing a progression bet on spin 14 and 15 on a single dozen, depending om the outcome.

I downloaded roughly 2050 spins from Wiesbaden and created 380 Sessions with 35 variances.

After spin 15, I remove the first 5 spins, I include spin 14 and 15 and wait for another 3 spins.. Another session can begin.

The probability of 2 bets on a single dozen is 54.8%.. My system created 72.5%. So a lots of Profit.

Now I will download another 5 days of Wiesbaden and will check if it is still profitable.

The Standard Deviation  after spins 13 and 15
