Well I don’t know how I have to sort RGB values with excel because once I sort by R the GB values are left unsorted.
What formula I should use?
I however read the actual chart files and it seems to have only 911unique colors, so you were close when said 910 
But if the extra patches are used in building the profile then I think it’s irrelevant that there are only 910unique patches.
Chromix color think has so many bugs that version 3 is unusable, only beta has some bugs solved. I wouldn’t touch the maxwell software with a ten yard pole. Global color management system, no no unless you have a money stashed for spectrophotometer not a colorimeter.
So it seems like for average Joe it’s better to pay 35-45$ for professional profile made with professional equipment and knowledge, than to buy cat in the bag.
Speaking about Chromix color ColorValet prices at $99 for RGB profile its a bit expensive to say the least.
