I could not get that period to work with my data + the TASS data.

I did finally capture some movement last night. See attached jpeg. I 
was doing more of an engineering run than a pure data gathering run -- 
thus the gaps in my data. Still, the variability is obvious.

It strikes me as weird that the other 6 hours of data I have is 
essentially at the minimum. It's like it hangs out at 11.45 and then 
rises up every now and then.

More data is needed!  =)
