It is the most efficient natural form, which is why its form is seen in planet, orbits, bubbles and atomic structures. A circle can never be drawn accurately, because it can only be drawn at a limited resolution by lines, which is not a true mathematical circle at all.
The circle with a dot in the centre is an ancient symbol for God; the scouts draw it on the ground to signal to others that they've gone
home. It is also a symbol for
centre. I believe the archer and darts player showing prowess in controlling the natural world is symbolically and metaphorically reaching the truth the closer they get to this centre. But this has little to do with time, and I must have too much of it!

Welcome and enjoy your stay
