Yes, you are, but maybe not the way you think.
Best practice isn't to center the wheel between the shoes, but to center the shoes based on the wheel's natural position.
Open your brakes totally so they don't get in your way, mount the wheel, then with the bike on a level floor, open the QR and jiggle the frame to settle the fork evenly on the axle, then close the QR to keep it there. This is the wheel's home position and it will return there reliably if you close the QR when the bike is vertical on level ground.
Now, center the brakes based on that, and you'll free of this minor headache.
