Rebuild command (select master curve ) the absence of (maximum deviation)

Would it be possible for the rebuild command to indicate the deviation in numbers between the constructed curve and the original curve in the case of using the (select master curve) option
the results are often better from what gives the command rebuild basic in rhino

I find this option great being that its operation is similar to the algorithm matchesrf uses to approach edges.
the only downside is the absence of the figures which indicates the deviation

thank you so much
