A few years ago, I tested :
- 435 At Home positions with 14 units : 25 correct PGs (5,7%).
- 4060 At Home positions with 13 units : 41 correct PGs (1%).
- 27405 At Home positions with 12 units : 276 correct PGs (1%).
- Only 50000 of the 142506 At Home positions with 12 units : 525 correct
I don't remember if i counted PGs with multiplicity.
(Results are not in a convenient form)
