Quoting ReposeAbout the correction, I think you're adding things up wrong. I only use correction for those columns where it's faster, and I found the break even at 7 adds, so it should work. All but the outer 1 or 2 columns can use it. Ah, good point. Only remaining issue is what to do with the borrow if the correction underflows. My brain hurts..
