... refreshed, optimized calculation timing
Added the buffered plot to be splined for + values.

Hello Jean,

For me, the first plot is working



but the second is not - cases() is complaining.



I could see that sigma2 went nuts (do not know why) and put eval() in front of it





I do not have the explanation of this - might be a bug.

Regards,
Radovan

1. Can't understand the error cases(,) [6671]
2. Make unit K was first problem , done well.
3. Doctoring for the spikes works and accelerates calculation timing.

Can you explain sheet. I was looking at creating a Langelier Saturation Index (LSI) for quick analysis and this appears to be going in that direction

The program is a dual iterative solver.
Give some more about Langelier saturation index.

Langelier saturation index [LI] has nothing to do wrt unbuffered.
As it looks, there are lot of those things already tabulated.
Wait and see if you can come up with some interesting stuff.
