I always use 16 B-Frames with Adaptive B-Frames for my Anime encodes it help a lot to make a 25 minutes episode fit in a 100MB file with a very good quality.
Well I use all very slow options of the encoder hehehe so I dont get this high diference on PSNR like you had on your test xD
On anime there is a lot of scenes that the imagem dont have any high movement for a lot of time and the anime image dont have a lot of details like a real movie and if your read the Stats file after doing the 1st Pass you can see a lot of places with more than 3 consecutive B-Frames and I even saw some scenes that the encoder used like 8-12 consecutive B-Frames.
I really think that you can use Adaptive 16 B-Frames without any problems when you are doing encodes that is going to have a small file size.
To get a diference of 1.0 PSNR that he got I really think that he dont used Adaptive B-Frames.
16 B-Frames without Adaptive you always lose a lot of quality.
