Jcl this is one area that Im still having alot of trouble, I spent a good few hours going through the manual reading about the different ways of optimizing and testing the data & Im confused to say the least.

Some questions I have:

1. How do you decide whether its best to use horizontal, vertical or WF optimizations?
2. How do you decide how many WFO cycles to run?
3. How do you decide if you datasplit what ratio's you should test and train in?
4. In what situations to use datasloping?

I have more but this would be a helpful start. Im sorry if these are dumb questions but from reading the manual this seems like the most important part of the process and I really want to understand this side of things as best as possible.
