This has already been addressed in part:
An observation and a question:
You still need to learn what a crew name is.
Why are you relying so heavily on dubiously accurate lithographs?
A: if this is a result of squashing the name into the available space, it isn’t very successful, is it? Half of the white crown has been lost, while the character preceding it and the cartouche name itself are missing entirely.
B: again the character preceding the white crown and the cartouche name preceding that character are missing entirely. The cartouche name would not be “below” the characters visible.
C: already addressed in part (for which see links above).
Second image: the hieroglyphs do not wrap around the “floor” block, any more than the cartouche does. You may find this cap helpful:
The upper surfaces of these granite slabs were not dressed to a level and the section through them appears to represent the central plane of the chamber and not the sides, so shows maximum height reached.
1: at this point the lithographs (large and small versions) and presumably the drawing by Perring on which they were based are very dubiously accurate. I am looking at the corresponding drawing by Rowe.
I hope this clears up what seems to be puzzling you.
