>> Everyone is different, but for me, broccoli has never given me a problem
!00% agree. Same here, I have been doing NSD for years and never had issues with Broccoli either. I would react within a few hours if there was a problem. As you say, everyone is different and we can only speak from personal experience.
Tomato puree often tests positive too though, but the starch is so little that it isn't a problem.

>> that last 10% will require you to tweak some more
Yes, that has been my experience also.
Well said Mr Foodie
