Safety precautions. I want to set a course that gets me closer, but not too close. The dashed line is just shown to see how it compares with the 'straight' intercept way. It is not used.

also forgot to say on the last post but the 7% over error by just doubling makes for a good early arrival time. if you want to trail them like a convoy then just wait while they pass and take notes of all the good high tonnage ships within it. arriving early is always good even if you want to shadow.

That works too. But with your way your 'early time' is directly proportional to the distance at the start, or how long the intercept took. So for long distance targets you will arrive more early than closer ones. I don't see the need for that. With this added circle to the method you should pass it a fixed stand-off distance every time.
