I don't understand what you mean...
Where does 8/16/48 come from? Yes, 192 would be the next number in that sequence and 960 would be next, but I don't see what that means for these parts.
The 10LDU or 20LDU are coming from how the curved part and the sub-parts are constructed, not from how many sections there are in a full circle.
