[Solved] Curve Fits more accurate than Cubic Spline ?

[VB6_to_PBx]

How do you choose the x-values, where the splines should start and end?

if you are asking me ?
its in the Zip File Link in post above

Splines will not work !!!

i've solved it sufficiently accurate enough for my needs
by blending Data thru Repeat Until Loops in 3 segments
using minimum of 6 XY Pairs to a maximum of 9 XY Pairs

discovered PureBasic created .EXE program is very fast using Arrays doing the above
great Programming Language and Forum Members willing to help out each other a bunch .

Update :
Picture of a Rough Draft of PureBasic program "Proof of Concept"
1600 Feet every 1.5 inches of distance in a Repeat/Loop ...very fast in PureBasic Code
using Repeat/Loops ... instant Data results as fast as you can Mouse click [Calculate] Button
