Let me compare it with the shallow cut 120-cell, which has 7560 stickers, but only 2520 movable pieces. The 120-cell halfcut has 14400 stickers, all of which are 1C pieces: there are 14400 pieces! The situation is similar to the Big Chop (half-cut edge turning dodecahedron). Even the shape of cuts on each dodecahedral cell is like the Big Chop. But this puzzle is still face turning, so it is a proper analog of Pentultimate.
