Perfect, yes.

I set ext-ecm large so that the internal avx-ecm can be used to high bounds, which is both multithreaded and vectorized. It must have accidentally got committed to git. If folks have AVX512F and therefore access to all three ecm versions, they will have to think about how to configure things with ext_ecm, prefer_gmpecm, and prefer_gmpecm_stg2.

The bug in tune was fixed last night; will hopefully get a new windows exe committed today.
