A circle on a projected surface is not a circle on the ground. A range ring drawn for a nominal 800 km measured at 851 north and 553 east, because the ring was a circle in screen space and screen space is not the ground. Both are drawn below and the discrepancy is printed. The trace holds a few sweeps and fades them, and says how much of what arrived it is keeping. Vertical writing is a script property, not a rotation. And the elbow is one element, so the sweep is continuous.
