Is there anything to regret there? I don’t see any, and betting on a specific number not changing it and not making gestures for other numbers will later turn out to be very boring, even if there happen to be winning sometimes. I would prefer to go with the rotation pattern where I can either be rotating the numbers I choose or I can just randomly be choosing them. Even if my previous number wins in the future when I did not choose it, I won’t regret it; rather I will consider it not to be my lucky day until my own lucky day comes.
