I'm going to revive this topic as I've just had an interesting question. posed to me...

The confirmation of the saturation curve can be done by using the nearest achievable data point when the exposure is done in passes/strokes. In the case above the operator would use the arc height value at 2 passes as a target value for confirmation.

When using the Curve Solver program by Dr Kirk the actual data points are often adjusted to generate a fitted curve. If the actual arc height at 2 passes was .0103 but the Curve Solver corrects the point to .0106, which should the operator use as the target: .0103 or .0106?

My answer is to use the adjusted value of .0106 as the target to be within +/- .0015. Do you agree Socrates?
