At present I either play 3 or 4 numbers using precognition. Whatever number I see is used for betting finales. I have posted a few videos of my play using this technique and have been very successful playing this way over the last 14-16 months. There is a thread on rouletteforum.cc that has been running for about the same length of time I have been doing this.
Just lately I have had success betting just 1 number and posted a video on Youtube in my channel a few days ago. I limited my bets to 8 spins per number and was able to win 84 units with 60 spins in the video I posted.
Since then the best I achieved is 273 units from 45 spins, this was playing with real money and I don't video real money play. I feel the videoing puts added pressure on me when playing with real money. Just a psycological thing I know, but I am not chancing it yet.
