I certainly agree that the information on just what the camera is doing when is not transparent. And it would seem to be in everyone's interest to make users aware of how to optimize settings. Of course, some of optimizing settings is user specific. I don't THiNK pdaf is used with m43 lenses in low sequential shot mode. I do find CAF to work quite well in high sequential shot mode.

PDAF is used in high and low speed burst modes.

Low will use CDAF if outside the PDAF array.

Low may use CDAF as a final check/hint.

Low is hybrid. CDAF is the primary focus system, PDAF used only to give a hint on what direction to go when CDAF starts hunting, it is like a final try to find direction where to go.

It slows down and cause delays when CDAF prediction AF algorithm made wrong prediction and hunts before asking from PDAF to where to go "okay, I lost it and I went to that direction and then I came back but couldn't find it, where I should go?" and to that PDAF says "it is X rotations to that way" and CDAF takes control again "Yeah, found it!" Until it misses again...
