Has anyone bought Jafco's system?

my biggest issue is being able to get my eye in to judge a 5r ball or a 4r. it can take me a lot of time. i hope that as i become more experienced that my brain and eye can judge the diiference between a 5r max and 4.75r max ball. i usually go conservative and judge a rev too late. its something that would improve my own margin a lot. i have learned to simply not bet when unsure of ball speed. a bet not made is money saved.
Main point of traditional VB is a good process of identifying the particular moment in the spin. On older wheels it can be done reasonably good. One of techniques is to watch for the “knee point” . It Is a moment where you can notice the ball suddenly takes longer time for a rotation. When testing I predicted thousands of spins where the RC predicts in particular ball rotation so I get feeling to judge when is the moment but, without RC that feeling can be easy lost.

Just watching new wheel in casino and defining ball rotation is hard. If the ball doesn’t jump much even with significant amount of mistakes you can still achieve advantage, but often the ball jumps distribution is wide and taking huge amount form advantage achieved by defining balls drop point. If the ball deceleration is smooth without “knee point” you need a good timer, or perhaps try VB2.

VB2 compensates for missed ball rotation, so it doesn’t matter if you predict in 6,7 or 8th ball rotation.

Understanding roulette wheel

If you have a wheel with deep pockets, you should learn to exploit it.
You say you have no idea about jumps charts, but that is a first thing you need to know.

In usual wheels with deep pockets have smaller ball jumps distribution? That is the biggest advantage you actually have. If on some other wheel it may be easier for you to predict, most likely wider ball jumps would reduce achieved advantage, lowering it under what you could have with the deep pockets wheel.

And yes, do you mind sending me a PM where did you find such easy wheels?
