Adam proved it again: he thinks in term of hours. For him, 23 eps = 23 hours, so 1 hour = 1ep. So it means, with his logic: 4A has 12 hours of eps, and 11 hours of ep for 4b. But, he also said one time (I'll try to find this tweet): for him, the eight ep is ONE ep of two hours. And, in terms of ep, 11 eps per half of seasons.

With Adam's logic: 4A has 12 hours of ep include in 11 eps (as he proved it again with 408A and 408B), and 4B has 11 hours include in 11 eps. Jane also supported this conception: for them, Fall is the ninth episode of S4, and Smash the Mirror is one ep of 2 hours (so ep 408A and ep 408B) => at the end we have 23eps/hours, 12 for the first half and 11 at the end
