I have been looking in the preset changes in the code before you posted updated guide and noticed possible mistake.
by default bpyramid is being set to 2 while the only documented values are 0 and 1
Code:
param->bpyramid = 2
and all other presets are setting it back to 1 except slower, veryslow, placebo
if bpyramid 2 exists and does something to improve quality it's strange that default has it set to 2 but slow to 1

btw. default keyframeMin = 0 seems a bit low is there some other mechanism that prevents too frequent I frames in fast changing images? is there a switch to change this like --min-keyint ?

Also if anyone knowledgeable is bored and could explain what some of those options do I would be very happy:
--max-merge - what are we merging? I'm guessing partitions but I would love to know more how and when this works.
--early-skip - what are we skipping?
--fast-cbf - what does cbf stands for again?
