ah sorry forgot to write, i dont really see this as a simplification or anything which should be run with non regression bounds, this basically just changes 1 -> 0

Well, I thought its looks better to have const auto for all correction values. 1->0 is just something I thought would be nice to have, but if the maintainer disagrees then so be it.
