He's talking about a schedule where you don't get to F5\F4 until day 39.

However, that would drag out the premerge period of the game ever more. I hate waiting 9+ epsiodes for the merge more than I dislike double boot episodes. Also double boots guarentee a certain parity, forcing both tribes to lose a member.

Also if they wanted more episodes they could just decrease the number of days between TCs. No need to pay the cameramen and crew to hang around 3 more days.
