Double Shot (2 actions)
You shoot twice in blindingly fast succession.
Make two Strikes, each against a separate target and with a –2 penalty.
Both attacks count toward your multiple attack penalty, but the penalty doesn’t increase until after you’ve made both of them.
So what's the attack/ penaltys?
Is it like power attack where you make 2 attacks but at -0 (as it uses. 2 actions at once),, then if you attack as your 3action it's at -10?
So I read it as like power attack but instead of no penalty, you take -2 on rack attack..or is it 1 atk -2, 2nd atk -7,3rd -10?
The part that really confuses me is this...
, but the penalty doesn’t increase until after you’ve made both of them.

It's -2/-2/-10/-10 if you do Double Shot -> Strike -> Strike.
Both attacks count toward your multiple attack penalty, but the penalty doesn’t increase until after you’ve made both of them.
Both attacks count for your MAP, so it would be -2/-7/-10/-10 except the feat explicitely says you don't increase your MAP until both shots are fired. So the second shot is not affected by MAP, but counts towards it for calculating the MAP for any subsequent attacks.
