Newcomer,
As with acquiring any skill, it will take time, effort and mistakes to cultivate a personal level of understanding and confidence. Tntea has provided a roadmap with several tools however; it becomes a personal responsibility to absorb the concept, then critique that method to coincide with a personal learning and / or application method.
I am a spatial thinker and to be honest, it has taken me some time to grasp the Vtrac concept. I too have dozens of questions. However, in all instances, I have found the answer just by re-reading tntea's lectures and studying my own numbers database. I don't know how else to explain this, but eventually, you will see trends with numbers. When that occurs, it will become almost second nature to predict the next set of vtracs with a level of certainty.
I have went through 1/2 a stack of copy paper working out the vtracs to try and understand the trends. I get better everyday however; I play the majority of my numbers on paper. I even think tntea suggests this until you build up your predicting accuracy. The key to this? It will hone your skills; you'll be able to see your errors or confirm your picks without an out-of-pocket cost. Your clear examples will come from your own predictions; it's the best way to improve- learn from your mistakes. I think we need to realize understanding and predicting vtracs is a skill, not a perfected process. Skill is aquired from tools, knowledge and most importantly, experience. We are all newbies compared to Tntea and the like.
Best of luck to you. In time, I think we'll all grasp the vtrac concept.
