Setting angle on new boots

So i just got some new boots (Ronix Kai) for my older Liquid Force board. They fit my board with the little adapter and they are very comfortable. My question is about setting the angle. I've read around a bit and since I am a beginnner I decided to set the back boot to 0 degrees and the front one to 18 degrees. My question is do I set each of the set screws on my front boot to 18 degrees, or one to 0 degrees and the other to 18 degrees? Sorry if this is some what confusing and I'm over complicating this, I just want to make sure I'm starting off on the right foot here (haha no pun intended)

Thanks guys

18 degrees is a lot and when you start to learn to ride switch you'll want your boots angled the same. Start with something closer to 12 degrees on both bindings on both sides of the bindings.

I have heard and always use the method of setting the board on the ground in front of you. Jump up in the air landing again with the board in front of you. Note the width and angle at which your feet landed naturally. Transfer this to your bindings on your board.

I think if you set one side to 0 and the other to 18 either the boot will be hanging off the heelside edge of the board or it won't fit at all. Set each side to the same number and centre the boot on the board.
