I can't believe all the advice here .......

Nobody shoot a bow the same. Look at all sports that have form as one of the main things that control how well the athelete performs and you'll see a lot of difference.

Michael Jordan shot the ball very differently than, say, Kevin Garnett does. Both are very good
Tiger Woods and Phil Mickelson have different golf swings- both are very good

As long as you're shooting the same way every time your arrows will go the same place everytime. I mean, you're shooting a machine - draw it back, hold it, put the pin where you want the arrow to go, and squeeze the trigger. Compounds are built to be shot very accurately.
