The big problem is that the target moves and the value taken at a time T1 are not the same at T2, T2=after we set the calculator...

Training must probably the best way to get experience.

Thanks again.

Like many things, keep it simple. Some like to make it overly complex. It doesn't need to be.
The Fast 90 attack method is a simple, excellent, and historical method to use for the attack.

The link Hamppupalaa gave you is a great one for plotting a convoy intercept too.
