With Get Spline Length i get wrong measurments for curly spline. How to get proper length?

The Get Spline Length node approximates the length of the spline, as there is no efficient analytical solution to that. The node provides a resolution option in the Advanced Node Settings to control the precision of the approximation. Increasing that should allow a more accurate computation of the length:
