What's the best number for a merge?

I'm a fan of Survivor, so I thought it was when half the people minus one was gone? Like half of 20 plus one equals 11 when you merge.

And shouldn't the Jury nearly always be seven? I've seen multiple reality shows, and nearly 80% have seven as the jurors.

(This isn't counting when there are 3/4 teams, because then you have multiple times to merge and maybe if a team lost all but two members they get shuffled into the others and stuff.)
