This would not have helped in the case you posted above. We can be smarter about the kind of problem you are seeing there… which is created by a shallow curve with weak data on one side (this is part of the lift for SGPro 4.0… to be smarter about getting good data). Doubling your step size will add some depth there… Smart focus or not, the fit quality was less than the allowable tolerance (98% it looks like). The minimum is currently at 99%… but may be adjusted before release. In the meantime, if, for some reason, increasing your step size leaves you with curves you feel good about, but SGPro says are no good, you can decrease the threshold size in sequences and profiles by adding this:
quadratic_fit_min_quality=0.98
Or whatever you feel appropriate, but keep it as high as possible…
