Interesting. I think your original 265 million domestic is close to how it turns out.
WOM is key but I notice on Screen Rant MOS isn't even listed in the Hot Topics listed across the top of the page. Of course internet "polls" aren't really too accurate.
Trailer clicks are an indicator but only that. The trailers have been great. But SR had a huge hit on it's trailers too. Hard to say.
I didn't know that SR was a huge hit with its trailers. Apart from WOM, the target demographic is also a key component in its gross. Take Iron Man 3 (produced by Disney): it is clearly intended for family audiences.(Some might disagree) The box office results clearly show this.(Friday-to-Saturday increase and Sunday-to-Monday decrease) In fact, this is one of the reasons why it is one its way to a billion; its attracting a really large audience.
In the trailers of MOS, there isn't a lot of an indication if it would match the family profile.
