I have just added a few more benchmarks, and here they come
it seems to be very recent so my only check based on 10 commits
didn't pick it up yet so they are not present in the summary table.
could well be related to 80% faster det()? ;)
norm was hit as well a bit earlier, might well be within these commits:
I will rerun now benchmarking for the rest of commits (was running last
in the day iirc)
