How I come up with my counts? Fair question.First, what I don't count. Nothing is counted during Probst's recaps at the start of each episode. Nothing said at Tribal Council is counted, not even voting confessionals. Final words aren't counted, except final words during an episode for a medical evacuation, with the episode continuing.
Re-used material from previous seasons isn't counted. During the introduction of the favorites this season there was a lot of that, Andrea and Brandon had new material confessionals during that segment. (I checked around before counting the Brandon confessional, he was wearing his Caramoan shirt so it was material from this season.)
Okay, the basics of how I count them. When a player has a confessional, then another player has a confessional, then the first player has or continues a confessional, that counts as 2. The focus shifted from the first player to the second player then back to the first player, that is reflected in the counts. If there is a long time break and then a confessional continues, without a break to another player, then I usually just count that as 1. If there is a change of subject I might count it as 2, that's where it becomes a judgment call.
