Reason behind SRK's films not opening to Bumper numbers in USA ? Check

Om Shanti Om in 2007 opened to record $1,764,131 from just 114 screens.

.

Even 3 Idiots failed to cross that number in 2009.

.

Then came My Name Is Khan (which was obviously expected a record start) did $1,944,027 in 2010. But i feel it should have crossed $2 mil as it was HUGE film compared to OSO 3 yrs ago. So not much jump in Business for MNIK.

Then offcourse Ra.One, Don2 all failed (though opened Big and were 2nd or 3rd highest at that time but not so BIG when you have SRK'a name attached to it)

.

Then came Chennai Express which did record weekend of $2,220,497 BUT took 196 screens while OSO and MNIK did that huge in 114/120 screens. So even though CE was record weekend but just few collections ahead of OSO even after 6 long years.

.

Then came Dhoom 3 which did take Massive opening of $3,423,508 which was missing for SRK after OSO, I mean opening upto its true potential.

.

Then came Happy New Year which did average business in weekend as per the film and SRK's name attached to it. It did $1,977,264 which was lesser than CE and similar to MNIK .

.

Then Came PK and did business upto its true potential $3,508,908 . Almost double than HNY after a month.

.

Then came Bajrangi Bhaijaan which did superb and above expectations $2,621,282 in weekend.

Then same year Prem Ratan Dhan Payo came and it also did very good $2,425,585 in weekend.

.

Then came Dilwale which did massive during weekend in Overseas ($8.5 mil) with clash BUT did just average business in USA and somewhat similar to Bajirao Mastani.

Dilwale - $1,920,402 (less than HNY, CE , MNIK)

Bajirao Mastani - $1,744,975

.

Now this year FAN came as a shock by doing just $1,382,869 which is way too less. Should have atleast done close to $2 mil as even Talaash opened to $1.5 mil in 2012.

.

So my question is , where SRK is going wrong as far as USA is concerned as He is doing Superb in Gulf and Very good in UK and rest of Overseas but USA is going down and down. Reason ?
