Anyway, maybe we are all reading too much into this preliminary, and somewhat noisy, data. We'll see how things look after better mounting.
I am only saying this based on pure empericism. I saw the clean data in shift after shift (D modes only!) as the derivative of the value became very large or very small. I do agree fully that this data is VERY noisy and significant improvement needs to happen here. Hopefully Kens mount will help. The next step would be replacing the accel followed by that nice clean power supply.
