I agree that this is a much better idea. How do we go about doing this?
I would be hesitant to use any second trend for making a noise budget. The trend generation stuff is not been vetted for low noise;
it may have any number of issues, like timing glitches, extra noise in the moving average, window bleeding, etc.
I feel like the path of least pain will be to just set up the mDV-nds2 system to grab data in chunks and downsample as necessary.
Also, we can ask JZ to implement server side decimation.
