We all love this chart and hope it comes to fruition. But I must point out that the bottom line is just a copy of the top line's slope fit to touch a single low. This doesn't make it a particularly strong channel. The bottom line may not have the same slope.
You are right, but as I said previously, this channel is purely arbitrary, and was really only included as a visual guide (for myself) - although, don't you think chart looks nicer for it?

This channel was in no way used to determine the projected ATHs that I have also posted.
