Comment:

 First and foremost, these are libx264 presets and not something FFmpeg
 manages. As such, any questions to how libx264 compression works should be
 directed to that project.

 To the issue at hand, there are no size guarantees for any of the presets,
 only speed/quality tradeoffs. It is very well possible that faster presets
 produce smaller files, albeit at a lower quality.
