All pyramids employ the seked. The seked is determined by the dimensions of the pyramid. What you seem to be following is Gay Robins' quarter-palm seked model, which says that the sekeds of all the pyramids are in increments of 1/4 palms. This is clear in the cases of Khufu's and Khafre's pyramids, but there are several exceptions, most notably Unas' pyramid. It is generally accepted as having a gradient of 3:2, thus a seked of 2/3 cubit, or 4 + 2/3 palms.

Even the Rhind Math Papyrus does not support Robins' rigid model. RMP 56 uses a pyramid with height 250c and semibase 180c, hence seked 18/25 cubit, or 5 + 1/25 palms.

That's not how the seked works. The seked of the pyramid is based on the semibase:height ratio. The seked was simply a means of getting the slope right so that the correct height was achieved.

As it turns out, the corner edge slope of Khufu's pyramid was very close to 9:10, but the architect/builders would not have been interested in the seked or slope of the corner edge. The 9:10 slope is simply a coincidence which follows from the fact that 99/70 is a close approximation to sqrt2.

The only possible case of their use or knowledge of the corner edge slope was the Bent pyramid lower portion. Its corner edge slope is 1:1, on account of the pyramid's profile triangle having a gradient close to sqrt2:1. (Actually, its slope is 10:7, and does not conform to Robins' quarter-palm seked model.)
