Sorry, I meant 32-2 =30, not 16 - 2 = 14 :-(
(I saved my results with -2, -3, -4, etc.)

- 435 At Home positions with 30 pieces : 25 correct PGs (5,7%).
- 4060 At Home positions with 29 pieces : 41 correct PGs (1%).
- 27405 At Home positions with 28 pieces : 276 correct PGs (1%).
- Only 50000 of the 142506 At Home positions with 27 pieces : 525 
correct PGs.
