Going back to the site I sourced earlier (
Link), there were 1,319 chips dropped that successfully reached the bottom of the board between seasons 29 and 39. Of those, 187 hit $10k, 322 hit $1k, 289 hit $500, 152 hit $100, and 369 hit $0. (22 got stuck along the way.) If we assume the distribution is symmetrical, we get:
5.8% - 11.0% - 12.2% - 14.0% - 14.2% - 14.0% - 12.2% - 11.0% - 5.8%
Relatively flat everywhere except the far sides, which makes sense when you look at the board and realize the corners are tucked away and hard to reach.
