I've read that Sticky a couple of times. As I read the threads on PDF conversions its gradually beginning to make sense.
For this particular issue the trigger words I was looking for were 'flow', 'join' or 'fold', I guess 'unwrap' sort of means the same thing, but I have predilection for antonyms over negations. Not sure I understand why a smaller factor is more 'aggressive', not that it matters
