I think my two subwoofers are now time aligned but I do not find the way to time align my mains with the sub group.
Advices very welcome.

I used 2 of your measurements for a new alignment tool analysis.
The attached file contains 2 alternative delay settings that I found. They are identical for SPL across the XO range and very similar to the SPL support provided by your current timing. There is thus no reason to assume that either of these alternatives would be a significant improvement.
