LA has started!
The "correct" filtering run yielded a smaller matrix (51.45M dim) and an ETA of 748h. See you in about a month! :smile: This will become a tight squeeze to complete it this year…

Yes, I saw the problem. My ideas were:

Change the target value.

Maybe I'll fix it tomorrow. I'm on mobile now and won't get to the computer today anymore.
