The SMPTE method is very conservative; it assigns class 3 (i.e. severe quantization) to any block where the largest AC - component is greater than 36. ffmpeg's DV encoder tracks AC bit + component is greater than 36. FFmpeg's DV encoder tracks AC bit consumption precisely, so there is no need to bias most blocks towards strongly lossy compression.
