While I agree, both impact and low point are located on the same plane, my contention is, from a players perspective, one cannot trace both and get the same result.

Give me a day or so and let me see if I can articulate this better.

Yes, no need, I see your point already

Basically, even though the Low Point Plane Line is located on the same Inclined Plane as the Impact Point Plane Line (the one we usually Trace), from the player's perspective, that Low Point Plane Line looks like the Impact Plane Line, hence we have a devastatingly bent Plane Line. The way to break through this illusion is to realise that you are Tracing a line which is under the ground. But why go through all this effort I wonder. Just use the basic Plane Line.
