Robo,
Yes, it will be interesting to wait for the ripples of Myst's epiphany to spread.
I think I understand what you are trying to do, but I just don't seem to see what you see. You see a 16 day EMA that has the same lag as the 12 day SMA, I see a 16 day EMA that reacts faster than the SMA, and has less extreme extremes. Perhaps if you would look at the 6 month version of your chart, you'ld see that the EMA actually runs before the SMA, and not with it or after it. I agree that the effect you are looking for is visible around the September dip, but it disappears quickly.
Regards,
Karel
