I think the thing I'm missing is what your overall goal is, autotuning perhaps?

If you take the nested loop I posted and after the inner loop, where the label Save to disk, etc. is located, and you put your code to analyze the data and recompute the coefficients, then have them update the local variables before the next loop runs. Then change so that the Run button controlling the case turns into some logic for how often you want to run or simply to run every iteration and control how often the outer loop runs.
