I have tried the same procedures you have spelled out in your previous emails.
My data has also not been linear, that is the Lab values, or in very small increments. I have tried to print the reading sample several times, and been very careful with it as well.
I have manually played with the numbers in the spreadsheet to make them a bit more linear and spread out a bit more evenly.�
After all this, I have tried to linearize the curve using the app, but the results are not linear.
It is really confusing to me this procedure, and I can certainly use some suggestions or help.
Thanks,
Moises

�According to your data you have three "flat spots" (or maybe even reversals) in you step wedge. These occur between steps 5 & 6, 11 & 12 and 15 & 16. In each case the consecutive L* values are too close to be differentiated. There's either something wrong with your printed wedge or something wrong with your measurements.
