comment How is Precision of Imported Data managed?
part of the issue is one of display, if you do RealDigits[x[[1]][[1]]] you'll see your 10^-14 digit is there.

Oh I see. Yes if the quotation marks are in the file thats ok.

comment For loop in Length computation code
a bit of an aside, but note Less is Sorts default, however actually giving it that argument slows it down a fair bit. Also Count[Differences@Sort[ ..], 1] beats Length@Split by a good bit.

comment For loop in Length computation code
FWIW in this case the Table result, although it looks more satisfactory is only very marginally faster than the For loop (avoiding memory issues tested with smaller NN like 10^6 ). Ultimately it seems if you want to brute force crunch it out the procedural loop is the way to go.

Just to clarify, what you have is not a valid CSV format file.

post actual code. Surely you don't expect folks to retype stuff from your notebook.

you might play with the discretization (.0001) to check that this converges to the NIntegrate result.

bugger. base is the original graphic, something like Line@Table[ curve02 , {\[Tau], 0,5 Pi , .01}] (or use parametric plot ).

comment Is there a way to outline text?
weird, RegionBoundary[reg]//FullForm shows the polygon data, but there is no evident way to programmatically extract it. Apply doesn't work.. on a MeshRegion

comment SeriesCoefficients expansion contradicts FullSimplify
clearly a b-g. SeriesCoefficient gives the correct result if you specify any particular n.

comment NSolve non-analytic function
suggest you plot θ - ArcTan, you'll see you have many roots. FindRoot gives you one at a time.
