Duncan Obviously there are. Some have " perfect knolidge".
Congratulations on your commitment !
If we can win without the hassle of VB why should we change to VB ? Probability suggests that there are some fake claims of AP being professionals in this forum .
Vb is just one level of understanding. There are wheels where it's useless, there are ..where it's not needed or imposible, or posible but not always. There are these where it's only way. Moral is simple , need to understand how it works and why and when.
Well, it is not obvious to me, Mr. P. Anyone can claim to be a professional roulette player .Whether
they actually are is debatable when we read of the amount of time they need to suss if a wheel is playable . Their need to calculate the data they collect then find that any conclusion reached can be undermined by " changing conditions ". Their need to avoid the casino's attention by forming a team.
Your admission that you also need to work out HOW it works and the WHY and WHEN only adds to the effort needed.
"Perfect knowledge" still faces the variability of the winning numbers and we gamblers should be cautious of making exaggerated claims .
It's much more easy then it sounds. There are factors that have to be present there. But in short, it's correlation. If there is correlation between predictors ( factors) and outcome , then player can do something , if not- not. Predictors or call them factors can be any, in some cases distances will work better( vb, ds), in some numbers themselves can be predictors, sometimes it's mix between numbers and distances, sometimes it's something other.
Correlation by itself is a bit of the dead end, besides finding it, need to understand situation in general. If you attack repetitive jump of ball , need to understand why it happens, if this " why?" stops to be present as a factor- look for something else... ets.
If you attack numbers instead of distances, need to understand why this numbers instead of any other numbers and when they are active ( any other factors wich may affect, or exact values of these factors).
As for vb itself, it's just a way to predict wich number gonna be at point of your choice in some moment in the future( with reasonable accuracy ). It's easy to do and control.
What gonna happen if ball does not go where you expect is a matter of the scatter study, ball jumps and their predictability is a matter of the study as well.
