SUDOKU... In the Round... Mystery Cache

Below is a nontraditional Sudoku Puzzle... I was first introduced to this style of puzzle at a PI Day Event in Seattle... The rules for completion are simple..

1. Once per ring,
2. Once per shaded double pie section, and
3. Once for each individual pie section including the section immediately across..

The rating is for solving the puzzle, the final is a camo'd pill container hidden as a typical 1.5/1.5...
