Hi Scott,

Sixteen isn't the answer I'm getting but I may be totally off with my estimate of 9-10. I haven't actually seen the answer the original poster believes to be correct yet. The answers I'm seeing from the LinkedIn postings are ranging from 4 to 17 with most posters choosing either 15 or 16. I don't know if they are proving the 96% failure or if I'm the one that is missing the boat.

I see the puzzle as resembling a plat map.
