<Did it ever prove useful?>
Long-term, yes, especially when everyone has the same count and you don't. I'm quite serious about this.
<Anywhere I read, there are folks not agreeing which wave it is now.>
Before the open several counts were possible.
<I did the count yesterday, 4 bloggers that I follow say we go up and 4others say we go down with next wave.>
Out of the eight, the first question to ask is: what criteria are they using to label a particular formation a "wave three"?
Next question: Out of the eight bloggers posting, who are taking the time to label "complex" 2's and "complex" 4's ?
Lastly--when four say up and four say down, I'd go with the ninth guy who calls for a sideways.
Right now we are still "channel huggin'" up.
Regards.
