CADJPY arc ratios and parabolas used like a leaf or canoe shape

Haven't test the parabola tool out enough to see how well it works. It would actually be a neat tool if they made a tool that look like a leaf. It's similar to an ellipse but comes to a point faster. It would also need a trend line running right down the middle of the leaf. Call it the "leaf tool" or the "canoe tool" ha
The ratios all work out nicely because they are all multiples of 1.144. ie. .764, .874, 1, 1.144
It means you can start on any arc ratio and they still work out. These are the same ratios as some other charts I have worked on in published.
