It's not perfect, but if you can scale the chart right a lot of arc swings can connect directly on the same radius swing. This eliminates, or at least minimizes the need for multiple ratios. I've seen this idea on many charts. The problem is backtesting has to be done to set the scale to make the swings fit.
The far right of the chart has my projection for where I think it's headed. Down for now ..but still up in the near future??
