As I am asking someone else to calculate this keyboard layout for me I am in no position to judge their software or methodology
Well, in this case, here are the results from the AdNW optimizer, using the bigram optimization and the corpus that comes with the software:

I have used the default scoring scheme. I attach the configuration file, in case you want to modify it. Which you probably will, as the scheme is completely different from CarpalX.
