I told you so!

As expected (at least as I expected), Federer has reiterated his objection to the use of the round-robin format in the wake of the mix-up at the Las Vegas Open:

Everybody knows I was against it (the round robin system) in the first place," said Federer. "It's actually very disappointing to see things like this had to happen first before you realise that the system is not going to work.

I'd say it's probably best to let the ATP to give the format a try. In a way, it's the best means for them to discover its flaws and eventually realize that it won't work that well after all.
