comment Generate a sequency of names such as a1, a2, a3
You need to use ToString[i] in Table otherwise you'll get what you say, i.e. "i" literally.

comment Integrate yields complex value, while after variable transformation the result is real. Bug?
But NIntegrate seems correct.

comment How can I obtain a smooth curve from my data but preserve two inversion points
You can try MovingAverage but that will change some features; for instance, the inversion points will not reach 0.

comment Contour plot with points and line together
If you call p1=ListContourPlot[...] and p2=ListPlot[the points you want] then you can just do Show[p1, p2].

comment Contour plot with points and line together
You could make a separate plot with the points only and then use Show.

comment Calling Sage functions from Mathematica
Could you please provide 1-2 examples of Sage functions lacking in Mathematica ? This will also attract more interest to your question.

Try Integrate[1/z, {z, 1, I, -1, -I, 1}].

comment Combine ImplicitRegion
Thanks for the suggestions, but can you modify uppR and lowR so they take the target region as an input ? I want to repeat the step start->target several times and it would be ideal if I can use NestList or similar.

comment How to include confidence intervals into ProbabilityScalePlot?
You could run a NonlinearModelFit to estimate the parameters; this will also provide confidence levels.

comment Mathematica integration failure - new or old?
The indefinite integral is evaluated instantaneously and it seems correct. The rest of the time, and possibly the bug, is due to the limits.
