[Optional]

I know it's early, but assuming the seeds are Djoko, Nadal, Federer, Murray, Del Potro, so Murray/DelP end up in the same quarter...

What is your estimate of fair odds on the top 3 to make the quarters?

5Dimes have a new option called an Open Parlay where you can specify the number of legs and fill them in as you go... allowing you to parlay their 12 matches up to the quarters. Just wondering if it's a +EV sort of strategy or not.

If they average -750 ($1.33) over those matches, the resulting odds are around +450. If they average -1000 ($1.10) it's around +320. I assume it will fall somewhere in between.

*Edit: and in case you think the average price will be lower. -1500 average results in ~+220
