Sebastian, you are right !
The peak appears at the curve center when the number of samples is 120 (approx) and keeps the distance of 60 samples to the end during further evaluation. Peak direction is related to the offset value and for a negative offset is positive. I wonder why there is no peak connected to the beginning of the sampling... It is strange, if you will gauss-smooth a constant value you will get such a peak. Normally nobody see it, it is about 0.00022 from the offset value.
As to the LOESS smoothing, I thought that it is to draw a smooth curve trough rare experimental points.
I used smoothing just to get stable indications of pressure and I have drawn the smoothed curve for a general interest. I could use an averaging of some last points, but I am not so fine with your 'subrange'. It would be nice to have negative counts as in Python...
