Ok, so only the outer two (green, then yellow) are used. Inner green is not necessary - Over-thinking it. Wording in image is correct, but extra innermost green section with inner line is not needed.
Formula, for sanity:
Core fin = 2/48".
+Smaller Ply per side = 1/48"(bottom) + 1/48"(top)
+Smallest Ply per side = 1/48"(bottom) + 1/48"(top)
