Yep, but this isn't what you were looking for?

only if your voting power is getting close to 100% will it follow one or many trails

Because with the threshold hive.vote (in my case) only casts a vote and follows the curation trails I chose when my voting power is getting close to 100% (i.e. is above 95%).

But I may be missing what you are saying, so sorry if this doesn't make sense 😅
