4 out of 13 doesn't sound like that much, but at one point it was 3 out of 8 of the remaining contestants (Brick, Jo, and Scott) having switched teams. Then when Dakota comes back, it's 3 out of 7 of the remaining contestants.

Plus, before this season, a team switch had never happened after episode two. It personally caught me off guard when it happened later than that, and then it happened thrice in one season.
