Yes I agree with all of that.
Regarding the yellow patch I feel that it is irrelevant in terms of the sequence of events.
If the gable stone is whitewashed then the cartouch came after the whitewash.. period.
If the whitewash was done in situ then so was the cartouche.
Therefore the cartouch is wrongly orientated to be consistent with AE writing convention. (vertical 90")
I'll be the first to admit that I am only working from photographs but the yellow staining under the Chick'n'Chisel is not consistent with the mineral migration and decay seen in other parts of the chamber.
Yes it is a question of "mark one" eyeball and digital images.
NASA seem to be happy with this method when viewing the surface of Mars.
I feel that all plastering/whitewashing was done after the gable stones were erected but the gable ends were still open.
Very little cosmetic attention to detail was paid to the plastering. Therefore I can only assume it had a functional purpose. An attempt to hermetically seal the chamber for reasons known only to the builders. This is a different issue and maybe worthy of a new thread.
Obviously after plastering and when the gables ends were still open there would have been the opportunity for a worker to enter and paint the contentious cartouche.
Problem is.. Why would he then have painted it sideways from top to bottom.
This along with other issues seems to present a whole firing squad of smoking guns.
