I'd think that going from 46 to 52 would have the opposite effect, make the planes smoother. I might even go with 60 (6 sider). If the goal is to be 8 then even more slop than that might be good, just _under_ the next level like 50 or 51 (in other words put the margin for error just below the 7-gon rather than just above the 8-gon). > Obviously there's no single value that will work for everything; I'd > be happy to hear other opinions on good defaults. Guess my vote would be 60 (or 59).
