@fabulousyarn - I'm seeing the exact same on/off pattern. However, I just finished a 5 hour keyword ranking session and I'm again seeing a lot of red. The #1 stuff is holding steady, but a lot of 2,3 and lower positions are moving -1 to -8 lower, so that explains some of the "OFF" part.
For a change I'd love to see a "green" trend.
