If quotes, no hyphen. EDIT: Actually, no hyphen at all for that setting.
The biggest mystery for a C175 file is the number of relations to target; but since you have an army of sievers and not much matrix power, I put the relations count a fair bit higher than I think strictly necessary. I think you could get away with 250M relations, but 270 should make a much nicer matrix. Last fiddled with by VBCurtis on 20200407 at 03:27
