About FO calculation

Hi,

1) This might be an issue with too recent compiler. But maybe a deeper issue related to a change of structure in the weight that was not passed to the lhe output mode. Myabe the best is to test with 2.9.6 here.

2) No the relative contribution should not be uniform.

Cheers,

Olivier
