Adam Scott - Genesis (Dead Heat)

I fully comprehend how dead heat works, the stipulations, etc. I took Scott +110 t20 on FD, $5455 to win $6k. He finished t19 along with 5 other golfers. FanDuel ultimately paid $4,500 on this, not allocating my initial wager to said winnings. 

So I was docked nearly $1k on a bet that didn’t lose. Again, I understand the concept of dead heat, but when is the initial wager not applied to a winning bet?  I’ve checked twitter and all golf cappers are counting the same wager as a win. 

What am I missing here?

 What you’re missing is that you DON’T understand how dead heat rules are applied. When Scott had to share the edge and going over top 20 with 5 guys (himself included) there were two spots available for five golfers in the tie (since 5 tied for 19th). Therefore, you automatically lose 3/5 of your original bet. They treat it as if you had 2/5 left at +110 odds. Do the math and it gets you close to that. You just learned how much it sucks to tie with others at the edge (while going outside of) a top 20. 

Books have to do this. What if the rest of the field shot that same number? Everyone would get top 20 payouts and their initial wager back. The scenario isn’t going to happen but having 10 tied there is common. Books would get killed and unfairly too. Don’t bet Top anything without understanding this because it’s a kick to the nuts getting surprised by it.
